feat: groups refactor Phase 1 — root RO/RW model + shared directories UI

Replace the upload boolean with per-root writable/removable/ejected flags.
Backend: new ops (update_root, eject_root, plug_root), MNP 1.1 protocol
messages, live RootSet updates so API always reflects current state, CLI
root subcommand (add/remove/set/list/eject/plug).
Frontend: SharedDirectoriesTable with optimistic toggle switches, eject/plug
in Files and Settings, upload gated on root.writable, ejected-root filtering
in all media apps, updated Create Group wizard, 10-locale i18n.
