feat: enhance log system with true deletion, noise filtering, and error boundaries

- Implemented `clear_logs` Tauri command to physically wipe local log files.
- Added a global `ErrorBoundary` to cleanly intercept React render loops (e.g. Error #185) and provide readable stack traces.
- Hardened `tauri_plugin_log` to filter out `webview`, `hyper`, `reqwest`, `rustls` log noise.
- Replaced the default browser right-click menu in LogsView with a custom native React menu for copying text securely.
