Subject: [PATCH] Fix Frigate parked car re-detection and enable writable
 config

Remove car-specific max_frames (was causing forget-and-re-detect loop)
and set stationary interval to 0. Use initContainer to copy configmap
into writable emptyDir so UI changes (zones, masks) persist at runtime.

+Fix Frigate repeatedly alerting on parked cars by removing per-object max_frames and setting stationary interval to 0. Make Frigate config writable so UI changes (zones, masks) persist within a pod lifecycle.
