Ship HDF EFFECT to PRO only, and clean the build for Play

Rename LIGHT GLOW to HDF EFFECT and gate it behind PRO: LITE renders the
chip greyed out with a PRO tag and cannot open its slider; restoration of
older settings that carry hdf > 0 still blocks export in LITE.

Play/licence pass:
- drop unused permissions (ACTIVITY_RECOGNITION, READ_MEDIA_AUDIO/VIDEO,
  SYSTEM_ALERT_WINDOW) and requestLegacyExternalStorage
- rename the Leica sims to LC STREETLIFE CLASSIC/VIVID, drop the brand from
  comments; fix app name text, canvaskit copyright, LICENSE owner
- remove expo-image-picker and expo-sensors (no JS import), delete dead
  exports (computeMatrixTint, cinemaSeasonName, base64 helpers,
  formatCoordinate)
- versionCode 3 / versionName 1.2.1, drop the personal email from About
- add docs/privacy-policy.html for the Play listing
