Before JPEG encoding and OTA upload, paint the configured [[zones]]
polygons (yellow) and the [trash].roi (red) directly onto a copied
Frame.rgb so uploaded alarm snapshots visually carry the calibrated
regions. Normalized coordinates are clamped to image bounds, the source
frame stays untouched for downstream runtime processing, and
non-alert/disabled paths are unchanged. Adds stdlib-only polygon
fill/outline helpers plus focused unit tests.

Add missing fields (event_code, camera_ip, started_at, ended_at,
dwell_seconds, is_discarded, alerted_at, etc.) to both batch_event
and case_event payloads. Introduce source_id config for payload
injection and infer_camera_ip to extract IP from RTSP stream URL.
