Samuel Newman 1e8ce36184 add fullHeight prop, fix Android bottom sheet behavior, keyboard handling
Native module:
- Add `fullHeight` prop to BottomSheetView on Android and iOS
- iOS: fullHeight sets detent to .large, skips content observation
- Android: fullHeight uses isFitToContents=false with expandedOffset=statusBarHeight

Android bottom sheet behavior overhaul:
- Switch normal sheets to isFitToContents=false with expandedOffset, enabling
  proper 3-state snapping (half-expanded ↔ expanded ↔ hidden). Previously
  isFitToContents=true prevented settling at half-expanded during gestures,
  making it impossible to swipe back down from expanded.
- preventExpansion sheets keep isFitToContents=true with maxHeight cap, plus
  a state callback safety net that bounces EXPANDED→HALF_EXPANDED. This
  catches an edge case where rapid content resizes during opening can invert
  the expanded/half-expanded offsets, causing the sheet to dismiss.
- Add requestLayout() after maxHeight changes in updateLayout() so the
  FrameLayout actually re-measures (fixes keyboard padding not resizing sheet)
- Set backgroundTint=transparent in the theme to remove Material3 surface
  tint that was visible in gaps between sheet and screen edge

Keyboard handling:
- Remove native keyboard expansion logic (insets listener, isKeyboardVisible
  tracking, manual STATE_EXPANDED on keyboard show)
- Replace with JS-side keyboard padding: ScrollableInner listens for RN
  Keyboard events and adds bottom padding equal to keyboard height
- Generalize useOnKeyboardDidShow → useOnKeyboard(eventName, cb)

Callers:
- Replace minHeight: screenHeight hack with fullHeight: true in EditProfile,
  ChangeHandle, AddAppPassword, ImageAltText, GifAltText, LanguageSelect,
  FollowDialog, GifSelect, StarterPack, Select, NewChat, ShareViaChat,
  DraftsList, WizardEditList, ListAddRemoveUsers, CreateOrEditList
- Remove unused useWindowDimensions imports
- ServerInput: simplify to just preventExpansion (was platform-specific)
- ImageAltTextDialog: remove old {height: 300} keyboard spacer hack
