fix: resolve Docker entrypoint permission test failures in CI

Browse Source 
- Update tests to accept dynamic UID range (10000-59999) instead of hardcoded 1001
- Enhance lock file creation with permission error handling and graceful fallback
- Fix database initialization test to handle different container UIDs
- Add proper error recovery when lock file creation fails
- Improve test robustness with better permission management for mounted volumes

These changes ensure tests pass in CI environments while maintaining the security
benefits of dynamic UID generation.
