adds a /pay/{token} redirect endpoint that generates a short URL
pointing to a stripe checkout sessions in setup mode. The TUI shows a QR
code and URL on the payment page so users can add a card via the browser
instead of entering raw card data over SSH.
the checkout.session.completed webhook saves the card to the database.
the TUI polls GET /api/v1/cards every second and auto-proceeds to
confirmation once the new card is detected.
also adds a dev.sh startup script that runs all four required processes.
(SSH server, API server, Stripe CLI listener, ngrok) in a single
terminal
Three bugs fixed, two of them from the last commit, one of them has been
long living.
- the cart query in the ViewInit handler used user_id on cart_items, but
that column does not exist, cart_items links to carts via cart_id. Fixed
by first finding the users cart and then querying items by cart_id,
which is how the reso of the cart handlers already do it.
- GetViewInit was missing the json.Decode call entirely. so the response
body was never parsed. This meant m.User was never set, blocking all
cart syncs and address saves, and the cart always loaded empty.
- after a successful order, the cart was never cleared locally even
though the server deleted the cart items. this meant that the user had
to quit and ssh back in to see the cart update. fixed by clreaing
m.Cart, m.CartCursor and m.ShippingInfo in the CheckoutResultMsg success
handler
prices stored as float64 could lead to rounding errors when converting to cents for stripe (19.99 * 100 = 1998.99... truncating to 1998). canged Coffee.Price to int, storing cents directly. Updated the seed data, fallback products, API handlers, and all TUI display code to be in sync with this change.
