Sell PRO as an in-app unlock, take shared photos, and let FX run negative

- One free Play app (com.locphamtran.recipescamera) with an expo-iap PRO
  unlock, replacing the paid apk for the store channel
- Android SEND/SEND_MULTIPLE share target feeds photos into the editor,
  on cold start and on resume
- BACK button in the TopBar and press-and-hold PEEK replace the chip row
- NOISE REDUCTION and SHARPENING accept -10: a negative SHARPENING softens
  the frame before the grain pass, a negative NOISE REDUCTION re-grains it,
  in the Skia engine, the live preview and the Kotlin export path alike
