feat(menu): Recovery scopes (#111), System IA (#105), drop Control Center (#110)

System is Connectivity / Devices / Recovery / Preferences under the same
six-entry root. Recovery lists desktop (HM), system boot, and BTRFS files
once each with cost labels. Control Center is gone: blur/gaps live in Look
& Feel; update checks and Bluetooth/Printing package toggles in Preferences
(with rebuilds). docs/RECOVERY paths updated.
