feat(logging): default to paused state and prevent performance hit via frontend wrapper

- Default LOG_PAUSED to true in backend.
- Combine tauri_plugin_log filters to drop backend logs when paused.
- Create frontend logger wrapper to intercept and drop logs before IPC when paused.
- Sync LogsView state directly with logger wrapper and handle initialization races.
