feat(vision): surface the recognized plate in the booth UI

The ANPR plate was saved (device_events kind:"read") but had no UI. Extend
GET /api/snapshots/by-identity/:identity to also return plates[] (plate, confidence,
region, direction, snapshotId, at) for that session, and render each as a cyan
"Plate: AA558EE 100%" chip in the SnapshotStrip — so it shows in both the booth
event-detail modal and the pay modal, beside the evidence photo, no separate screen.
Deduped by plate+direction; session:read gated; i18n sq+en.

Verified: by-identity returns plates[] for a seeded read (200, AA558EE 0.999 Albania
entry). Build + lint green.
