Miscellaneous fixes (#23201)

* sync filter entries with track and listen labels

- Auto-populate `audio.filters` from `audio.listen` instead of the full audio labelmap, matching how `objects.filters` is keyed by `track` (no longer need to populate the full audio labelmap, which was added in #22630)
- Synthesize the matching filter entries in the settings form on load so each track/listen label shows its collapsible after a profile is selected, since the backend's auto-populate only runs at config init

* translate main label for lifecycle description with attribute

* reject restricted go2rtc stream sources when added via api

* add env var check function
