Fix Frigate parked car re-detection and enable writable config

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.
