Nick Berardi ade34b7da6 fix(alexa): v3 API compliance, fan speed, security panel, and camera streaming improvements (#2083)
* fix(alexa): v3 API compliance fixes, fan speed, and security panel control

Bring the Alexa Smart Home integration in line with the current v3 API.

Tier 1 (malformed responses / missing handlers):
- BrightnessController: report brightness under the Alexa.BrightnessController
  namespace instead of Alexa.PowerController so Set/AdjustBrightness responses
  match the advertised capability.
- SmartVision ObjectDetection: flatten the doubly-nested payload.events array.
- SecurityPanelController: add Arm/Disarm directive handlers (previously
  advertised but unhandled, silently falling through to a fake success), wired
  to armSecuritySystem/disarmSecuritySystem. Enforce the spec rule rejecting a
  direct ARMED_AWAY -> other armed-state transition with AUTHORIZATION_REQUIRED.
  Drop the advertised FOUR_DIGIT_PIN authorization, which Scrypted cannot honor.
- Auth failures now return an Alexa INVALID_AUTHORIZATION_CREDENTIAL
  ErrorResponse instead of a bare HTTP 500 that Alexa retries and surfaces as a
  generic skill error.

API modernization:
- EndpointHealth: downgrade to the documented v3.1 / connectivity-only shape and
  stop emitting the undocumented battery property (and 3.2 version), which risks
  the whole capability being rejected.
- Fan: add Alexa.RangeController (Fan.Speed, 0-100%) for devices implementing the
  Fan interface, alongside the existing PowerController on/off.

Cleanups:
- addAccessToken: initialize event.endpoint as an object, not an array.
- Hoist getArmState to a shared export instead of duplicating it.

Bump version to 0.4.0.

* fix(alexa): improve camera stream quality and connectivity

Tune the WebRTC negotiation for Alexa camera sessions.

- Resolution: raise the proxied stream cap from 720p to 1080p. The previous
  1280x720 screen hint forced the transcoder into medium-resolution mode for
  every endpoint, so even an Echo Show 15 or Fire TV only received 720p. 1080p
  lets larger displays render sharply while the transcoder still clamps width
  and falls back to 720p when H.264 High can't be negotiated. We cap rather
  than send the uncapped source, since Alexa's directive carries no display
  hint and a 4K stream would waste bandwidth on smaller Echo devices.

- Two-way audio: only advertise isFullDuplexAudioSupported when the camera
  implements the Intercom interface. Advertising full duplex on a one-way
  camera makes Alexa set up a return mic path that goes nowhere.

- TURN: stop unconditionally disabling TURN, and expose a "Use TURN Servers"
  plugin setting (on by default). Alexa sessions are proxied and often cross
  NATs where a TURN relay is the only path that connects; combined with
  disabled trickle ICE (all candidates in the initial SDP), omitting the relay
  candidate left NAT-blocked sessions with no fallback. When enabled, TURN
  usage defers to the WebRTC plugin's own setting, matching the Google Home
  integration; disabling it force-disables TURN for Alexa sessions only.

Bump version to 0.5.0.
