CarDash 1.2.2 fixes the car volume on FYT/Syu head units and stops the volume card from jumping back to 100%.

- **Package:** `com.wasp.cardash_launcher`
- **Version:** 1.2.2 (versionCode 22)
- **ABIs:** arm64-v8a, armeabi-v7a, x86_64 (universal APK)
- **Signing:** project debug key matching all prior releases
- **SHA-256:** `fed6d1818cfd28b19c0e568652ad14f44ce4bf15291a635f73fd97efe1ef5a35`

**The bug**
On FYT/Syu-based head units (Joying, Junsun, Teyes, Atoto and similar Chinese
firmware) the amplifier belongs to the MCU. Android's media-stream volume is not
what the driver hears, so `setStreamVolume` was accepted and ignored. The card
then trusted the old read-back and snapped straight back to 100%, which made the
car's real steps (10, 20, …) impossible to reach from the dashboard.

**The fix**
- CarDash binds the car's own `com.syu.ms` toolkit/sound module and sets the same
  master volume the car's OSD uses (0–36, MCU command `C_VOL`). It subscribes to
  the MCU level, so the dashboard and the car's knob now follow each other.
- If the car reports an old level after a write, the card keeps the requested
  value and marks it with `?` instead of snapping back.
- Units without the Syu service keep the Android path, now with an extra
  `FLAG_SHOW_UI` write that can reach vendor volume panels.
- Volume diagnostics show the raw level/max, minimum, fixed flag, control source
  (`syu`, `syu-wait`, `system`) and vendor state. Long-press **Media volume**.
- No new permission, root or manifest change. The car's own knob and
  steering-wheel handling is untouched.

**Also in 1.2.2**
- Jellyfin **Favorites** tab, album-page heart and the playing-album Home
  shortcut.
- Jellyfin **Streaming quality** setting: Direct or 320/256/192/128 kbps MP3.

**Verified**
- 149 tests pass; `flutter analyze` clean; debug and release APKs build.
- **The MCU volume path still needs the real-car test.** After installing,
  long-press **Media volume**: `source syu` + `vendor ready` means the bridge is
  active. `source system` + `vendor unavailable` means this is not a Syu unit.
