Miscellaneous fixes (#23017)

* add ui to camera config update topics enum

* add mqtt to camera config update enum

* ensure cleanup runs when an event end skips post-processing

* end any in-progress audio events when audio detection is disabled

we already end in-progress audio events when we disable a camera, but this mirrors that logic for specifically disabling audio detection

* Improve GenAI metadata

* fix invalid recording segment topic being misrouted to the valid handler

* Add confidence default to avoid unnecessary field causing issues
