feat: Align automations with Home Assistant triggers and conditions (#2527)

Split automations into HA-style `triggers`, ongoing `conditions`, and
`actions`, with compatibility migrations for existing Advanced Camera
Card configs.

## Summary

At a glance (details below):

- **Added** `triggers:` -- a required, HA-shaped block: stock `state` /
`numeric_state` / `template` plus card-specific triggers (`camera`,
`view`, `fullscreen`, ...).
- **Added** the HA-native `if` / `then` / `else` action.
- **Removed** `actions_not` (replaced by `if` / `then` / `else`).
- **Removed** the ambient `advanced_camera_card` template namespace (use
`acc` instead).
- **Changed** the trigger template surface to a top-level `trigger.*`
variable (as in HA); the nested `acc.trigger.*` paths are removed.
- **Changed** `conditions:` to ongoing gates only -- they no longer wake
an automation, and change-only forms (`config`, valueless `camera` /
`view` / `state`) become triggers, not conditions.
- **Changed** action templates to render per step, so a later action
sees state an earlier one changed.
- **Compatibility:** HA-shaped YAML is accepted (singular keys,
single-or-list, `and` / `or` / `not` shorthand, `entity` / `entity_id`).
- **Migration:** existing configs upgrade automatically; anything that
cannot be converted faithfully is recorded under `__UPGRADE_FAILURE__`
for manual fixup.

## Breaking Changes

### 1. Automations now require triggers

Before this PR, `automations[].conditions` served two roles:

- They decided whether the automation should run.
- They also acted as the thing that woke the automation up.

After this PR:

- `triggers` wake the automation.
- `conditions` only gate it at the instant a trigger fires.

Most existing automations are migrated automatically from `conditions:`
to `triggers:`.

### 2. `actions_not` is retired

Legacy `actions_not` is replaced by an HA-style `if` action with `then`
/ `else`.

Faithful conversions are automatic. Cases that cannot be faithfully
converted are recorded under `__UPGRADE_FAILURE__.automations` and must
be migrated manually.

### 3. Template surface aligned with Home Assistant

Two related template changes, both auto-migrated:

- **Top-level `trigger.*`.** Automation actions now receive a top-level
`trigger` template variable, like Home Assistant. Legacy nested paths
such as `acc.trigger.state.to` and
`advanced_camera_card.trigger.camera.to` are migrated automatically when
they appear inside template strings.
- **The ambient `advanced_camera_card` template namespace is removed.**
The long-form ambient namespace (`advanced_camera_card.camera`,
`advanced_camera_card.view`, `advanced_camera_card.config`) is retired
in favour of its shorter `acc` alias -- supported since v7.1.0, and the
only spelling the new trigger surface uses. Existing templates are
migrated automatically by rewriting the `advanced_camera_card.` prefix
to `acc.`.

### 4. Trigger-only condition forms are no longer valid conditions

Some legacy "conditions" were really change detectors. These are now
triggers only:

- `condition: config`
- valueless `camera`
- valueless `view`
- valueless `state` / picture-elements state condition with neither
`state` nor `state_not`

These are automatically promoted in automations and stripped from
overrides/elements where they would no longer be meaningful as ongoing
conditions.

### 5. Template truthiness now follows Home Assistant behavior

Template conditions and template triggers intentionally use different
truthiness rules, matching HA:

- A template condition passes only when the rendered value is `true`
(case-insensitive), matching HA's `condition.py`.
- A template trigger uses HA's broader `result_as_boolean` coercion: a
non-zero number, or `1` / `true` / `yes` / `on` / `enable`
(case-insensitive), counts as true.

### 6. Action templates render when each action executes

Action templates are now rendered per action step, not once for the
whole sequence. This means a later action can see card-local state
changed by an earlier action in the same sequence.

The `trigger` context is fixed for the automation run. HA entity state
updates still depend on the frontend receiving updated HASS state over
the websocket.

## Automatic Migrations

### Automation `conditions:` to `triggers:`

Simple legacy automation:

```yaml
# Before
automations:
  - conditions:
      - condition: fullscreen
        fullscreen: true
    actions:
      - action: custom:advanced-camera-card-action
        advanced_camera_card_action: substream_on
```

```yaml
# After, automatic
automations:
  - triggers:
      - trigger: fullscreen
        fullscreen: true
    actions:
      - action: custom:advanced-camera-card-action
        advanced_camera_card_action: substream_on
```

State conditions become HA-style state triggers:

```yaml
# Before
automations:
  - conditions:
      - condition: state
        entity_id: binary_sensor.front_door
        state: 'on'
    actions:
      - action: custom:advanced-camera-card-action
        advanced_camera_card_action: live
```

```yaml
# After, automatic
automations:
  - triggers:
      - trigger: state
        entity_id: binary_sensor.front_door
        to: 'on'
    actions:
      - action: custom:advanced-camera-card-action
        advanced_camera_card_action: live
```

Multiple conditions become both triggers and ongoing conditions:

```yaml
# Before
automations:
  - conditions:
      - condition: camera
        cameras: [front_door]
      - condition: fullscreen
        fullscreen: true
    actions:
      - action: custom:advanced-camera-card-action
        advanced_camera_card_action: substream_on
```

```yaml
# After, automatic
automations:
  - triggers:
      - trigger: camera
        cameras: [front_door]
      - trigger: fullscreen
        fullscreen: true
    conditions:
      - condition: camera
        cameras: [front_door]
      - condition: fullscreen
        fullscreen: true
    actions:
      - action: custom:advanced-camera-card-action
        advanced_camera_card_action: substream_on
```

The flattened trigger list is an implicit OR. The retained `conditions:`
list is an implicit AND checked when any trigger fires.

### Trigger-only legacy conditions

Legacy `config` conditions become `config` triggers:

```yaml
# Before
automations:
  - conditions:
      - condition: config
        paths: [menu.style]
    actions:
      - action: custom:advanced-camera-card-action
        advanced_camera_card_action: status_bar
```

```yaml
# After, automatic
automations:
  - triggers:
      - trigger: config
        paths: [menu.style]
    actions:
      - action: custom:advanced-camera-card-action
        advanced_camera_card_action: status_bar
```

Trigger-only leaves are removed from retained `conditions:` blocks
because they no longer describe an ongoing state.

### `actions_not` to `if` / `then` / `else`

```yaml
# Before
automations:
  - conditions:
      - condition: state
        entity_id: input_boolean.camera_alerts
        state: 'on'
    actions:
      - action: custom:advanced-camera-card-action
        advanced_camera_card_action: live
    actions_not:
      - action: none
```

```yaml
# After, automatic
automations:
  - triggers:
      - trigger: state
        entity_id: input_boolean.camera_alerts
    actions:
      - if:
          - condition: state
            entity_id: input_boolean.camera_alerts
            state: 'on'
        then:
          - action: custom:advanced-camera-card-action
            advanced_camera_card_action: live
        else:
          - action: none
```

If the legacy automation had no conditions, or only trigger-only
conditions, `actions_not` is dropped because the old `else` branch could
not be reproduced as an ongoing predicate.

### Trigger template paths

```yaml
# Before
message: 'Door is {{ acc.trigger.state.to }} from {{ acc.trigger.state.from }}'
```

```yaml
# After, automatic
message: 'Door is {{ trigger.to_state.state }} from {{ trigger.from_state.state }}'
```

Path rewrites performed automatically:

| Old path                   | New path                   |
| -------------------------- | -------------------------- |
| `acc.trigger.state.entity` | `trigger.entity_id`        |
| `acc.trigger.state.from`   | `trigger.from_state.state` |
| `acc.trigger.state.to`     | `trigger.to_state.state`   |
| `acc.trigger.camera.from`  | `trigger.from_acc.camera`  |
| `acc.trigger.camera.to`    | `trigger.to_acc.camera`    |
| `acc.trigger.view.from`    | `trigger.from_acc.view`    |
| `acc.trigger.view.to`      | `trigger.to_acc.view`      |
| `acc.trigger.config.from`  | `trigger.from_acc.config`  |
| `acc.trigger.config.to`    | `trigger.to_acc.config`    |

The same rewrites are applied for the older
`advanced_camera_card.trigger.*` namespace.

### Ambient template namespace

Any remaining long-form ambient `advanced_camera_card.*` references
(outside the trigger surface) are rewritten to the `acc.*` alias:

```yaml
# Before
title: 'Now viewing {{ advanced_camera_card.camera }}'
```

```yaml
# After, automatic
title: 'Now viewing {{ acc.camera }}'
```

## Manual Migration Cases

### `__UPGRADE_FAILURE__.automations`

If a legacy automation cannot be converted faithfully, the original
automation is recorded under:

```yaml
__UPGRADE_FAILURE__:
  automations:
    - ...
```

These entries require manual migration.

The main known case is legacy `actions_not` with a condition whose
trigger can only fire on a rising edge, such as:

- `condition: template`
- `condition: screen`
- `condition: numeric_state` without an entity-backed state to watch

Those conditions can start the `then` branch, but cannot reliably start
the `else` branch when they stop matching.

### Unsupported HA conditions and triggers

This PR aligns the card with HA where supported, but it is not a full HA
automation engine.

Unsupported HA condition families include:

- `time`
- `zone`
- `sun`
- `location`
- `device`
- `condition: trigger`

Unsupported HA trigger platforms include:

- `event`
- `time`
- `time_pattern`
- `sun`
- `zone`
- `calendar`
- `webhook`
- `tag`
- `device`
- `mqtt`

The card-specific camera `triggers:` feature (which auto-selects and
wakes the card on camera events such as motion) is a separate feature
from automation `triggers:`, despite the shared word.

### Trigger IDs and variables

HA keys such as `id`, `alias`, and `variables` are accepted so pasted HA
YAML validates, but they are ignored by the card. There is no
`trigger.id` support in this PR.

## New Compatibility Features

This PR also makes card config more forgiving for HA-style YAML:

- `trigger`, `condition`, and `action` singular keys are accepted and
normalized to `triggers`, `conditions`, and `actions`.
- Single trigger, condition, and action objects are accepted where lists
are expected.
- `if`, `then`, and `else` accept a single item or a list.
- Composite condition shorthand is accepted:
  - `{ and: [...] }`
  - `{ or: [...] }`
  - `{ not: [...] }`
  - `{ condition: [...] }` as an implicit AND
- State conditions resolve expected state values that name another
entity, matching HA/Lovelace behavior.
- Both `entity` and `entity_id` are accepted on state and numeric
conditions and triggers (a superset of HA's two dialects), so there is
no forced rename.
- `state_not` remains supported as a card/Lovelace-friendly extension.

## Trigger Payloads

Automation action templates receive a top-level `trigger` object.

For stock `state` and `numeric_state` triggers:

```yaml
trigger.platform
trigger.entity_id
trigger.entity
trigger.from_state
trigger.to_state
```

For template triggers:

```yaml
trigger.platform
```

For card-specific triggers:

```yaml
trigger.platform # "acc"
trigger.type
trigger.from_acc
trigger.to_acc
```

The card does not currently expose HA's `id`, `idx`, `for`, `attribute`,
`above`, `below`, or `alias` trigger fields.

BREAKING CHANGE: Automations now follow Home Assistant's `triggers:` /
`conditions:` / `actions:` model. Automations require a `triggers:`
block and `conditions:` no longer wake an automation; `actions_not` is
removed in favour of an `if` / `then` / `else` action; the nested
`acc.trigger.*` template paths and the ambient `advanced_camera_card`
template namespace are removed (use the top-level `trigger.*` surface
and the `acc` alias); trigger-only condition forms (`config`, valueless
`camera` / `view` / `state`) are no longer valid conditions; and
template-condition vs template-trigger truthiness now follow HA.
Existing configs are upgraded automatically where a faithful conversion
exists; anything that cannot be converted is recorded under
`__UPGRADE_FAILURE__` for manual migration.
