Miscellaneous fixes (#23610)

* Handle back seeking going to previous clip

* scope /recordings/unavailable query to the caller's allowed cameras

* listen for config updates in activity manager

* don't set search after awaited request

Intentionally do NOT setSearch() to mark the open event submitted. This runs after the awaited request, by which point the user may have closed the dialog; re-setting the parent's selected event would resurrect it and the force-open effect would reopen it (see #23599). The local "submitted" state covers the open card, and mutate() updates the events cache so the grid and any future open reflect the result.

* fix ruff

#23201 removed pathlib import but for some reason it's just now causing ruff to fail
