chore: update .gitignore and enhance backend and mobile app functionality

- Added mobile app build directories and configuration files to .gitignore for cleaner repository management.
- Improved error handling in diaryMemberController by requiring diaryDateId and memberId query parameters.
- Refactored DiaryMemberService to log tag IDs instead of raw values for better debugging.
- Enhanced TournamentParticipantsTab and TournamentTab components with improved touch-action properties for better user experience.
- Updated mobile app's gradle.properties and build.gradle.kts for compatibility with AGP 9.x and Kotlin 2.1.21, including new dependencies for Coil and UCrop.
- Refactored MainApplication to simplify initialization and improved MainActivity to handle dependencies more robustly.
- Updated various UI components in the mobile app to enhance layout and functionality, including MemberDetailScreen and MemberEditScreen.
