Whiteflow v0.1.0: testnet launch

Whiteflow's first release: the product as it runs at whiteflow.org on Whitechain testnet. Testnet only: test USDT, no real money.

What's in it

• Gateway: hosted checkout, payment links and payment pages, invoices, QR codes for the counter, discount vouchers, multi-currency prices, reports and settlements, signed webhooks, API keys, a one-line pay button and an SDK.
• Settlement: each payment settles to the merchant's own wallet in the same transaction. Customers pay no gas. A flat 0.10 USDT fee per payment.
• Capital: cash advances and invoice financing, repaid from sales on chain.
• AI assistants: the whiteflow-mcp server on npm, a Claude Desktop extension, and one-click installs for Cursor and VS Code (whiteflow.org/mcp).
• Site: pricing, status, about, contact, privacy and terms pages; WCAG 2.2 AA fixes and security headers.

In the last batch (#75)

• Each payment attempt is recorded before it is relayed, and attempts with an unknown outcome are settled from the chain, so a single-use link can't be paid twice.
• Rate limits on the payment and chain-reading routes, capped request bodies, and the old wallet sign-in routes removed.
• Plain wording for customers and merchants, one date format, and a new footer, 404 and error page.
