feat: Add microphone audio processing constraints (#2708)

## Summary

- add optional microphone constraints for echo cancellation, noise
suppression, automatic gain control, and channel count
- request configured values as non-mandatory `ideal` constraints
- expose privacy-safe microphone capabilities, requested constraints,
and applied settings in card diagnostics
- document the new configuration and add schema, microphone manager, and
diagnostics tests

## Motivation

The card currently calls `getUserMedia()` with `audio: true`. This
leaves echo cancellation, noise suppression, automatic gain control, and
channel count implicit.

Browser and device behavior differs. Explicit processing defaults can
regress microphone gain or amplify noise on some devices. This change
therefore keeps all processing constraints optional and configurable.

## Configuration

```yaml
live:
  microphone:
    constraints:
      echo_cancellation: true
      noise_suppression: true
      auto_gain_control: false
      channel_count: 1
```

Configured values use `ideal` constraints. A browser can ignore
unsupported values. Card diagnostics show the browser capabilities, the
requested constraints, and the reported applied settings.

## Backward compatibility

- existing configurations still use `audio: true`
- no audio-processing defaults are added
- explicit `false` values are preserved
- diagnostic output excludes device and group identifiers

## Validation

- focused microphone, schema, and diagnostics tests: 46 passed
- full test suite: 7,177 passed
- lint passed
- format check passed
- typecheck passed
- unused-code check passed
- production build passed

The optional constraints were also tested successfully with an iOS Home
Assistant Companion client and a go2rtc-based full-duplex intercom. This
is a client microphone-processing change only. It does not add backend
audio denoise.

| Option | Default | Description |
| ------------------------------------ | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `always_connected` | `false` | Whether or not to keep the microphone connected while the card is running. By default the microphone is connected when a [two-way audio](../usage/2-way-audio.md) call needs it and disconnected when that call ends. Setting this to `true` connects it at card load and never disconnects it, which avoids the connection setup on the first call at the cost of the browser reporting the microphone as in use for as long as the card is running. |
| `audio_processing` | | Audio processing applied to the browser microphone. See below. |
| `auto_mute` | `[]` | A list of conditions in which the microphone is muted. `hidden` will automatically mute the microphone when the card becomes hidden (e.g. browser/tab change, or the card scrolling out of view). Use an empty list (`[]`, the default) to never automatically mute the microphone this way. The microphone is always muted when a call ends. |
| `auto_unmute` | `[]` | A list of conditions in which the microphone is unmuted. `call` will automatically unmute the microphone when a [two-way audio](../usage/2-way-audio.md) call is started (or answered for inbound calls). `visible` will automatically unmute the microphone when the card becomes visible again. By default this list is empty, so the microphone stays muted even after answering (push-to-talk) -- tap the microphone button in the call overlay to talk. Unmuting only has an effect during a call: at any other time nothing can carry the audio, so the request is ignored. |
| `mute_after_microphone_mute_seconds` | `60` | The number of seconds after the microphone mutes to automatically mute the inbound audio when `live.auto_mute` includes `microphone`. |
See [Using 2-way audio](../usage/2-way-audio.md) for more information about the very particular requirements that must be followed for 2-way audio to work.

### `audio_processing`
These options process microphone audio in the browser before WebRTC sends it to the camera.
Each option maps to the matching browser [`MediaTrackConstraints`](https://developer.mozilla.org/en-US/docs/Web/API/MediaTrackConstraints) property, requested as an `ideal` value so the browser never rejects the microphone for being unable to honor it.
| Option | Default | Description |
| ------------------- | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `auto_gain_control` | `auto` | `true` or `false` to request browser automatic gain control, or `auto` to leave the choice to the browser. Set this to `false` when automatic gain control amplifies unwanted background noise. |
| `channel_count` | | The preferred positive integer channel count. Use `1` to request mono audio. Unset leaves the choice to the browser. |
| `echo_cancellation` | `auto` | `true` or `false` to request browser echo cancellation, or `auto` to leave the choice to the browser. |
| `noise_suppression` | `auto` | `true` or `false` to request browser noise suppression, or `auto` to leave the choice to the browser. |
?> The card passes these settings to the browser, but it is the browser -- not
the card -- that decides whether to honor them, and it may silently ignore any
of them. Once a call has been made, the
[diagnostics](../support.md?id=diagnostics-missing-in-issue) show the microphone
`capabilities` and the `settings` the browser actually applied.
