auto-claude: subtask-6-1 - Run flutter analyze to ensure no errors or warnings

Fixed all 39 analyzer issues:
- Removed unused import (animation_system.dart in collapsible_routes_sidebar.dart)
- Removed unused element (_buildActionButton in dark_mode_map.dart)
- Fixed unnecessary non-null assertions on AppLocalizations.of(context)
- Removed unnecessary type checks in providers.dart
- Used super parameters for key in navigation_tc_dialog.dart and status_colors.dart
- Replaced print statements with debugPrint in providers.dart and logging_interceptor.dart
