Gitea sends `requested_reviewer` (singular) field for `review_requested` webhook actions, not always the `requested_reviewers` (plural/array). The processor only checked the array form, so `usersToNotify` was always empty and no notification was sent. Also add more INFO-level logging for debugging the review_requested path. Fixes: manual mappings worked but were never reached because the processor never added the reviewer to the notification list.
