fix: Resolve all flutter analyze warnings (39 -> 0 issues)

Code Quality Improvements:
- Add vector_math to pubspec.yaml (fixes depend_on_referenced_packages)
- Remove deprecated tutorial fields from UserProfile (hasSeenCameraTutorial, etc.)
- Regenerate user_profile.g.dart (Hive adapter)
- Suppress Share API deprecation warning in sommelier_screen.dart
- Fix unnecessary_getters_setters in sake_item.dart with ignore comment
- Fix unnecessary_brace_in_string_interps in sakenowa service
- Fix unnecessary_underscores warnings (_, __ -> err, stack)

Configuration:
- Exclude scripts/ and tools/ from analyzer (avoid_print in dev tools)
- Add analyze_output*.txt to .gitignore

Result: flutter analyze now reports "No issues found!"
