feat: integrate Stripe payment with bugfixes and active timeout cancellation
- Add Stripe payment provider with Checkout Session flow - Payment provider abstraction layer (EasyPay + Stripe unified interface) - Stripe webhook with proper raw body handling and signature verification - Frontend: Stripe button with URL validation, anti-duplicate click, noopener - Active timeout cancellation: query platform before expiring, recover paid orders - Singleton Stripe client, idempotency keys, Math.round for amounts - Handle async_payment events, return null for unknown webhook events - Set Checkout Session expires_at aligned with order timeout - Add cancelPayment to provider interface (Stripe: sessions.expire, EasyPay: no-op) - Enable stripe in frontend payment type list
