Miscellaneous Fixes (#21072)

* Implement renaming in model editing dialog

* add transcription faq

* remove incorrect constraint for viewer as username

should be able to change anyone's role other than admin

* Don't save redundant state changes

* prevent crash when a camera doesn't support onvif imaging service required for focus support

* Fine tune behavior

* Stop redundant go2rtc stream metadata requests and defer audio information to allow bandwidth for image requests

* Improve cleanup logic for capture process
