fix(report): align the report modal with the reference theme 1:1

- read preset reasons from the real source (ban_preset_reason via
  UserRuntime::ban_settings); the previous injection read a
  nonexistent report.categories key, so backend reasons never showed
- rebuild the modal on the reference markup contract: edit-header
  warning header, reason chips toggling the reference .active class
  (focus color), other-reason textarea, violation link, description,
  but-average modal-buts footer
- add image evidence upload gated by user_report_img_s: new
  /report/upload-image route reusing the comment upload handler with
  its own permission, preview/remove UI, up to 3 images appended to
  the report content
- render the backend report notice (user_report_desc, sanitized HTML)
  inside the modal
- widen the dialog to the reference 600px desktop geometry and share
  the form-upload preview styles with the order review modal
- extend the report contract test accordingly
