WIP: Improve SQLite initialization and error handling

- Implement XDG Base Directory Specification for data storage
  - Use $XDG_DATA_HOME (defaults to ~/.local/share) for data files
  - Add proper directory permissions (700) for security
  - Fallback to ~/.timesafari if XDG paths fail

- Add graceful degradation for SQLite failures
  - Allow app to boot even if SQLite initialization fails
  - Track and expose initialization errors via IPC
  - Add availability checks to all SQLite operations
  - Improve error reporting and logging

- Security improvements
  - Set secure permissions (700) on data directories
  - Verify directory permissions on existing paths
  - Add proper error handling for permission issues

TODO:
- Fix database creation
- Add retry logic for initialization
- Add reinitialization capability
- Add more detailed error reporting
- Consider fallback storage options
