feat(anpr): subscriber-entry bridge + admin disable toggle

Wire the lane camera's vehicle event into the gated subscription flow: on a
vehicle/active push from an opt-in (config.anpr) camera, AnprBridge pulls a fresh
snapshot, runs ANPR, applies a stricter entry confidence floor, debounces, and —
matching the plate to a subscription BEFORE emitting — emits a kind:"plate" read.
The existing ReadDispatcher -> SubscriptionFlow then signs the entry/exit and opens
the barrier. A plate is never the sole authority: it routes through the same gate
(active/window/blocklist/car-count) as any credential. Fail-soft, fire-and-forget,
subscriber-only by construction. Field-verified end to end (plate AA504LX opened the
entry barrier and appended a signed vehicle_entry).

Add an admin master switch (site_config.anpr_entry_enabled, default ON) in Site
Settings that disables ONLY the barrier-driving bridge; advisory snapshot-ANPR and
lane busy/free are unaffected. Read live per event, so toggling takes effect with no
restart. Migration 0013 (additive ALTER ADD COLUMN, default 1).

- New: apps/server/src/anpr-entry.ts (AnprBridge) + tests (9)
- hikvision-alarm.ts hands vehicle detections to the bridge (fire-and-forget) + wiring tests (3)
- server.ts reorders the read flows above the hik-alarm registration
- snapshot.ts exports buildCamera for reuse
- env: VISION_ENTRY_MIN_CONFIDENCE (0.85), ANPR_DEBOUNCE_MS (12000)
- site route + SiteSettings checkbox + i18n (sq/en parity)
- wiki: lane-presence-and-anpr-entry / lpr-camera / index / log -> BUILT
