Support permission requests in direct Guardian review (#58903)

Browse Source 
## What changed

Allow `guardian_review` to assess a final recorded `request_permissions` call without granting permissions. Build the review action using the same permission request preparation as live review, while continuing to reject earlier permission requests in the recorded history.

Return no assessment when the approval policy is `never` or granular policy disables permission requests.

## Testing

Add coverage comparing live and direct permission review inputs, plus tests that disallowed requests return no assessment without contacting the reviewer.
