Rotate camera frames before encoding while accounting for Camera2 texture transforms. Align camera timestamps with MediaRecorder and cover capture duration, tracks and rotation with regression tests. Include LibVLC ProGuard rules and update documentation and changelog.

enter the same ordered upload/retry/quota/replay pipeline as desktop.
Devices without a supported camera/encoder report a startup error.
Camera frames are rotated through an OpenGL surface before encoding, so both
live playback and replays have upright pixels without relying on rotation
metadata (not supported by the MPEG-TS recorder). The sensor, front/rear lens
and display orientation are sampled when capture starts; portrait output swaps
width and height. Camera2 may already include sensor rotation in the
SurfaceTexture transform; only the remaining rotation is applied by OpenGL.
Keep that device orientation during a broadcast, or stop and
start a new broadcast after turning the device.
A camera/microphone foreground service and a partial wake lock maintain the
broadcast when PostIt is backgrounded or the screen locks. Its ongoing
notification returns to the app and offers **Arreter et publier**. Stopping
