Fix feedback submission and form label accessibility bugs

- Fix feedback silently discarded when text is empty: Remove early return
  that prevented submitFeedback.mutate() from being called when textarea
  was empty. The thumbs up/down vote (isPositiveFeedback) is now recorded
  even without optional text feedback.

- Fix form labels replaced with non-semantic paragraph elements: Replace
  <p> tags with proper <Label> components with htmlFor attributes for the
  Request, Subject, and Message form fields, restoring click-to-focus
  behavior and screen reader association.
