v1.0.15: ON_CHANGE file watching, browser fix, rich notifications

- Add FileWatchService for real-time ON_CHANGE sync (FileObserver for
  direct paths, ContentObserver for SAF content:// URIs), 5s debounce
- Fix remote browser stuck spinner: cancel in-flight jobs on navigation,
  reset entries immediately, add Retry button on error
- Fix browser reuse bug: LaunchedEffect key now includes initialPath
- Fix WebDavProvider: rethrow XML parse errors (no more silent Empty
  folder) and URL-decode file names from href
- Notifications now use BigTextStyle showing per-file-type counts
  (Uploaded/Downloaded/Deleted) matching Autosync notification style
- Wire FileWatchService into BootReceiver and HomeViewModel toggle
- Register FileWatchService in AndroidManifest
