feat(share): rebuild share rank with dart:ui Canvas generator

Replace RepaintBoundary widget capture approach with a pure
dart:ui PictureRecorder + Canvas implementation.

- Add share_card_generator.dart: generates 1080×1920 PNG via
  Canvas without embedding any widget in the tree
- Remove share_rank_card.dart (widget approach no longer needed)
- Remove GlobalKey, _buildHiddenShareCard, RepaintBoundary,
  _fmtEp from profile_screen.dart
- Simplify desktop + mobile Stacks to direct ScrollViews
- Fix Android GPU compositing timing crash (no retry needed)
- Add avatarImage.dispose() to prevent GPU memory leak
- Guard byteData null return with StateError
- Replace MaterialIcons bolt with Unicode  (tree-shake safe)
- Align tier in share text with tier rendered on card
