The gov-fee email now lists exactly what the amount covers (full breakdown) so
the customer can check it for accuracy, with two clear actions: a ✅ pay link and
a ❓ 'something looks wrong' link to /order/dispute.
New /order/dispute page shows the fee breakdown and lets the customer describe
what's wrong; it opens an 'issue' support ticket pre-tagged with the order
(amount + label + their note) via /api/v1/tickets, so ops corrects the fee
before any payment is taken. The /order/pay page also shows the itemized
breakdown and a dispute link.
