Georgia Payments (TBC Bank — TBC checkout)

Create a payment link in GEL for Georgia via TBC Bank (T-Pay). Buyer pays with cards, TBC internet banking, Apple Pay / Google Pay via TBC Bank checkout. Returns a hosted checkout URL the buyer opens to pay — payment completes automatically, no confirm step. Bring your own credentials via HTTP header (x-tbc-api-key; free test credentials from developers.tbcbank.ge never move real money). Money always flows buyer→TBC Bank→merchant; this service never touches funds.

Check whether a Georgia payment (created by create_payment_link) has been paid. Queries TBC Bank directly — pull-based, no webhook needed. paid=true when status is PAID.
