feat(ui): persist log filter preferences in settings file

This commit improves the log viewer by persisting user filter preferences
across page navigation and application restarts.

Changes:
- Add log_filter_level and log_filter_source fields to AppConfig
- Store filter preferences in settings.json instead of localStorage
- Ensure filter preferences survive app restarts and page switches
- Fix clippy warning: use &Path instead of &PathBuf in normalize_path

The filter level and source selections are now saved to the persistent
settings file, providing a more reliable storage mechanism for Tauri
applications.
