After a process crash, Android could restart a recorder service and reconnect the UI to it without the model ever calling init() with the saved settings. The very first access to the `settings` lateinit then threw UninitializedPropertyAccessException, crashing the UI as soon as it bound. Expose `hasInitializedSettings()` on IntervalRecorderService and have BaseRecorderModel detect stale services on bind, drop them, and start a fresh one instead of binding to invalid state.
Dashcam users repeatedly asked (upstream issues) for evidence metadata to be visible inside the recorded video itself, not just as sidecar data: a wall-clock timestamp, and optionally GPS coordinates. Add separate, default-off settings for time and location overlays (with curated timestamp formats and location-permission handling), and a CameraX video effect that renders the configured overlay via an OpenGL pass on each frame before it reaches the encoder.

feat: burn time and location overlays into recorded video
Dashcam users repeatedly asked (upstream issues) for evidence metadata
to be visible inside the recorded video itself, not just as sidecar
data: a wall-clock timestamp, and optionally GPS coordinates.
Add separate, default-off settings for time and location overlays
(with curated timestamp formats and location-permission handling),
and a CameraX video effect that renders the configured overlay via an
OpenGL pass on each frame before it reaches the encoder.
Code changes by Claude Opus running inside Pi.dev. I built and tested this commit, it works fine in my phone.
Depends on #158 to build and run.
Contains #161, should be rebased on it.
