Task 07: System storage API and composition

Expose the complete Storage contract and replace the old Office GC wiring with the composed service.

Acceptance

• Every spec endpoint returns the documented status/shape, validates Go-cache/Docker confirmation and busy states, and publishes/persists matching System jobs.
• Backend composition supplies all providers, activity coordinator, cleanup worker, health checks, and startup reconciliation with correct start/stop ownership.
• The unconditional office/infra sweep no longer runs; optional scheduling is available with Office disabled and waits one interval before its first run.

Verification

cd apps/backend && go test ./internal/system/storage ./internal/system ./internal/backendapp ./internal/office/infra
