Startup mode default/last-session; GPS watermark default OFF; shutter OFF truly silent

- Settings STARTUP MODE chips (AsyncStorage startup_mode): default = clean camera
  + PROVIA neutral 4:3, last = restore full session look.
- initSession: resolve sim-* recipe ids via FILM_SIMS (fix clobber of session
  ratio/adjustments to 4:3 canonical); restore via setSelectedRecipe not
  applyRecipe so user tweaks (frame/geotag/ratio) survive restore.
- applyDefaultStartup turns GPS watermark OFF (user-requested default).
- Shutter: OFF must not play click on must-play-policy devices. VisionCamera
  v5.2.3 HybridPhotoOutput.kt plays MediaActionSound itself gated by
  (enableShutterSound ?: true) || mustPlayShutterSound — on Xiaomi mustPlay=true
  so OFF still clicked. Both capture paths now gate on enableShutterSound != false.
  node_modules patch not trackable -> artifacts/patches/vision-camera-shutter-silent.patch.
  Verified on Xiaomi 12S Ultra: log SND user=false -> play=false; cold-start
  DEFAULT shows GPS WATERMARK OFF.
