feat: add createdAt timestamps to check-in logs and improve i18n translations

- Added createdAt timestamps to various check-in log entries in checkinService.ts for better tracking.
- Updated i18n translations in Models.tsx to improve user experience with accurate Chinese translations.
- Reduced default page size in ProgramLogs.tsx and ProxyLogs.tsx from 80 and 100 to 50 for better performance.
- Enhanced ProxyLogs.tsx with memoization for filtered logs and summary statistics.
- Implemented support for parsing Unix timestamps and PostgreSQL-style timezone offsets in checkinLogTime.ts.
- Added comprehensive tests for database proxy query wrapper in index.proxy-wrap.test.ts to ensure functionality.
