fix: persist feedback/comments across page reloads on review page

Feedback was saving to DB but never loaded back on page revisit.
Three-point fix:
- Backend schema: add feedback list to OutputRowResponse
- Backend service: eagerly load feedback relationship in preview query
- Frontend mapper: map latest feedback entry to OutputRow.feedback
