feat: Add TPLink camera engine support (#2257)

* Related #2183

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Introduce `tplink` camera engine with relative PTZ via button
entities, add icons/docs support, refactor to `EntityCamera`, and extend
tests/schema/factory for auto-detection.
> 
> - **Engines**
>   - **New `tplink` engine**:
>     - Add `Engine.TPLink`, schema support (`engine: 'tplink'`).
> - Implement `TPLinkCameraManagerEngine` and `TPLinkCamera` (relative
PTZ via `button.*` entities; no presets/zoom; stop is no-op).
> - Update `engine-factory` to create/auto-detect `tplink` (platform
`tplink`).
> - **Refactor**
> - Replace `BrowseMediaCamera` with `EntityCamera`; update `motioneye`
and `reolink` cameras and `motioneye` engine type checks.
> - **UI/Icons**
> - Add `tplink.svg`; wire into `IconController`; update docs icon copy
script.
> - **Docs**
> - Add `tplink` to engine capability and live-provider matrices; new
`tplink` section incl. PTZ note; add custom icon entry.
> - **Tests**
> - Add TPLink camera/engine tests and factory tests; remove obsolete
`BrowseMediaCamera` test.
