feat: icons on the buttons, delivery, payment, status and Kanban

- Buttons: add to cart (bag with plus), go to payment (lock), remove from
  the cart (bin).
- Delivery: a pin for pickup in Franca, a truck for home delivery.
- Payment: card and QR code on the methods, copy on the PIX code, a clock on
  its countdown, a check on the confirmation.
- Status: a check when the files are sent, check, alert, redo and cross in
  the quality list instead of Unicode symbols, and a check on finished steps.
- Kanban: a truck or pin for where an order goes, a speech bubble on the
  WhatsApp link, a download arrow on the file buttons.

All Lucide shapes drawn inline, as in the header.
