feat: redesign the Kanban and keep test wording out of production

Kanban: tabs for production, quote review and payments/integrations; compact
cards with products, metres, print-file status, delivery and time in stage;
an order panel with stage progress, one main action, a correction reason in
place, items with a preview drawn from the approved layout, final-file
approval and the history as a timeline. Quote review gets a list and a pane;
payment issues resolve in place; integrations show their real state, Tiny's
connection with a read-only "Testar conexão", and a readable send log. The
previous Kanban is kept in git tag ui-v1 and is no longer served.

Production wording: the customer portal no longer says it is a local test
environment outside the local stack; the checkout no longer tells customers
to use the Kanban or shows internal stage codes; sign-in, session, quota and
print-file messages are Portuguese and never say "local". A simulated freight
price is refused outside the local stack until a real freight provider
exists, so production only offers pickup.

The browser suite drives the new tabs and panel and still checks the whole
upload, quote, payment and production journey. Full CI sequence passes locally.
