Offline tab as Files view, automatic background sync, sync notifications

- Offline tab is now FilesView(offline: true) over a FolderBrowser interface (FilesController / OfflineController) sharing controls, tiles, thumbnails - Synced files follow the Files Cache rule (default: refresh every 15 min): per-account WorkManager jobs, in-app timer, resume and pull triggers; root-etag shortcut skips full walks when nothing changed - Single sync at a time (shared lock); logging out stops that account's sync - Sync safety: PROPFIND failures skip the path instead of deleting local files - Mirror empty folders and remove deleted ones; drop synced paths deleted on the server; missing local files are re-downloaded - Notifications: silent per-account sync notifications, "Background sync notifications" setting, audible upload/download completion - Files refresh in place (no spinner flash); retry after network returns - Fix sync badges not updating (shared native status stream), "Sync off" on launch (eager providers), Files Cache section moved under Device Sync Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

+/// The configured sync targets (folders/files) with a "stop syncing"

+/// inline list, moved into a sheet here so the main Offline view can look
+/// like a plain Files-style browser instead of always showing this
