- Implement Election Materials order-form revisions (docs/lucid *(2).pdf):
  new "permanent ballot list" question, and a Yes/No/Unsure nonprofit-status
  question now asked on both blue-envelope permit-ownership branches, with
  a matching migration, model/repository regen, and validation updates.
- Box the /request-order form and heading in the site's form-panel style.
- Shrink the site footer.
- After request-order and order submission, redirect to / with a flash
  message instead of re-rendering the form page inline.
- Skin the continuation and order-confirmation emails to match the site's
  branding (logo, navy header/footer, purple accents) instead of plain
  unstyled HTML.

Extract email sending into OrderMailer, answer-to-model mapping into
OrderDetailsAnswersMapper, label mapping into OrderDetailsLabels, and
generic dictionary-based field validation into core/lib.Validations.asp
(alongside a small lib.JsonResponse helper), replacing the private
helpers previously duplicated inline in OrderApiController and
RequestOrderController.
