Remove `ai_access_token` column from AppSettings: 16.5 - migration
Split from #422037 (comment 1515160245)
While removing the PAT field from UI will be completed in %16.4, we will need three releases (%16.4 , %16.5 , %16.6 ) to fully remove the column safely.
So we will track this process separately.
