release(android): 1.7.9 — Android 14+ crash + YouTube 152 fixes

Rebuilds and redistributes the player APK so the fixes actually reach devices:
- #5 Android 14+ mediaProjection FGS crash (committed in source but the SERVED
  ScreenTinker.apk was a stale 1.7.7 build from before it — modern devices
  couldn't launch the app at all).
- YouTube error 152 (embed base domain).

versionCode 11->12, versionName 1.7.8->1.7.9, VERSION file 1.7.7->1.7.9 so the
update check offers it; signed with the same release key (OTA signature check
passes). Verified on a Pixel 10 / Android 16 emulator: launches without crashing,
YouTube plays.
