fix: Resolve Flutter compile errors across 15 files

- Fix GroupCategory enum duplication (group.dart re-exports from cluster.dart)
- Fix stitchVideos arg count (use stitchVideosLegacy in quip_recorder)
- Fix enhanced_quip_recorder: getter/field conflict, XFile→File, static calls, CameraLensDirection, setState syntax
- Fix blocking_service: imports, ShareXFiles, SnackBar content, nullable bool
- Fix audio_overlay_service: path_provider import, getOutput() stub, fade icons
- Fix enhanced_beacon_detail_screen: flutter_map v8 interactionOptions, const constraints, Uri.parse
- Fix private_capsule_screen: add api_provider import
- Stub e2ee_device_sync_service (packages not in pubspec)
- Add generic post()/delete() helpers to api_service
- Fix repost_service: remove static, migrate StateNotifier→Notifier (Riverpod 3.x)
- Fix repost_widget: Repost? null assertion, RepostState type, Post field names, timeago, context param
- Fix sojorn_swipeable_post: close if-block, remove undefined _updateChainSetting
- Fix draggable_widget_grid: use this.widget for isEditable/theme/callbacks when ProfileWidget param shadows
