Miscellaneous Fixes (#20848)

* Fix filtering for classification

* Adjust prompt to account for response tokens

* Correctly return response for reprocess

* Use API response to update data instead of trying to re-parse all of the values

* Implement rename class api

* Fix model deletion / rename dialog

* Remove camera spatial context

* Catch error
