Add a per-relay "Test" control on each saved controller in /setup so an admin
can prove barrier wiring without a vehicle. POST /api/setup/test-relay pulses a
barrier relay — but because a physical open with no matching signed command is
the fraud signal, the route SIGNS a barrier_open_command (reason setup.relayTest,
source manual, attributed to the acting admin) BEFORE it fires. Reconciliation
then reads the open as explained, not an anomaly, and there's an audit trail.
- Admin-only (site:update), CSRF-guarded; fires only against a SAVED controller
(real id → clean attribution; also stops a redirected/unsaved config from
opening an arbitrary host's barrier). Sign-before-fire; a pulse failure is
reported, not a 500. radarAlert relays (lamps) are excluded from the UI.
- New reason code setup.relayTest in @parking/shared (+ EN template); sq/en keys.
- EventLog constructed before setupRoutes so the route can sign.
- Integration test (stub controller, no hardware): RBAC 403, CSRF 403, signed
barrier_open_command on success, 400 unknown relay w/ no ledger row, 404
unknown controller, 400 bad relay value.
