feat: add encrypted online settings backup keys

Add immutable client-encrypted settings snapshots with independent MDD2 capability keys so fresh installs can restore configuration without transferring backup files. Keep credentials encrypted end to end, preserve queues and history during import, and avoid exposing identifiers in request URLs or errors. Include the persistent API with quota, rate limits, crash-safe storage locking, durability checks, and end-to-end race and recovery coverage.
