[ENG-10042] fix(registry): moderators cannot approve registration updates (#887)

- Ticket: [ENG-10042]
- Feature flag: n/a

## Purpose
Fix an issue where moderators could not approve registration updates  
because the mapper was selecting the wrong schema response (first one 
instead of the one with `pending_moderation` state), and the UI did   
not properly handle revisions awaiting admin approval.
