feat(anpr): per-camera auto-open toggle (anprAutoTrigger) for shared lanes

A shared entry/exit lane has both an entry and an exit camera on ONE lane: a
subscriber driving IN is admitted by the entry cam, but the exit cam sees the same
car leaving its frame and phantom-EXITs the occurrence just opened (its back plate).

Separate RECOGNITION from AUTO-OPEN per camera:
- config.anpr (unchanged) = run snapshots through the recognizer, record the plate
  (evidence), BOTH directions — stays on.
- config.anprAutoTrigger (new, absent ⇒ on when anpr is on) = may THIS camera
  auto-open the barrier. Set false on the shared-lane exit cam: it still recognises
  plates but never auto-triggers. The bridge gates on it (anpr-entry.ts), before the
  poll loop.

UI: a "Auto open/close on subscriber plate" checkbox under ANPR in the camera setup
(shown when anpr is on); persisted true/false so a park can explicitly disable it.
i18n sq+en (also corrected the now-stale anprHint "never opens a barrier" wording —
it does, via the bridge). +1 server test (anprAutoTrigger=false → no snapshot, no
read); 172 green. Documented the two toggle levels (site-wide + per-camera) in
lane-presence-and-anpr-entry.
