feat(command-palette): add quick toggles, sync, and auth actions

Adds 13 reactive quick toggles (24h time, animations, blur adult, cover
modes, hover cover, schedule list, reverse sort, data saver, notifications,
language, title format cycle, outbound link target cycle), three sync
actions (push/pull/disable), and login/logout entries gated on auth state.
Names reflect current state so the palette doubles as a status surface.
