Miscellaneous Fixes (#21063)

* Fix history management failing when updating URL

* Handle case where user doesn't have images that represent all states

If a user selects all imags and can't proceed we show a warning that they can still proceed but the model won't be trained until they get at least one image for every state.

* Still create all classes

We stil need to create all classes even if the user didn't assign images to them.

* fix camera group access for non admin users

changes from previous PR wrongly included users from the standard viewer role (but excluded custom viewer roles)

* Adjust threat level interaction to be less strict

* use base path when fetching go2rtc data

* show config error message when starting in safe mode

* fix genai migration

* fix genai

* Fix genai migration
