fix: correct invalid segment topic matching in CameraWatchdog

Browse Source 
`topic.endswith("valid")` also matched `"recordings/invalid"`, routing
invalid segment messages to the valid branch. This kept
`latest_invalid_segment_time` permanently at 0, preventing the stale
recording restart logic from ever triggering on a stream of corrupt
segments.

Fix by anchoring the suffix with a leading slash so each enum value
matches exactly one topic type.
