fix: modal save button + missing translations

- Replace form="id" cross-element approach with requestSubmit() for
  reliable save button wiring in modal footer
- Re-call _bindDirty after validation-error re-render so dirty guard
  is preserved across save attempts
- Translate missing Dutch strings: Order saved, Error saving order,
  Question details, View
