feat(STATE-WP-0064): add consistency sweep remote-all API endpoint

Expose POST /consistency/sweep/remote-all so activity-core can trigger
the workstation ADR-001 remote-all sweep via the bridge tunnel pattern.
Records consistency_sweep_remote_all progress events and documents the
cutover runbook while the local custodian-sync timer remains interim.
