/** Create the x402-gated pricing routes.
 *
 *  Uses @x402/hono middleware for V2 protocol support including:
 *  - PAYMENT-SIGNATURE / PAYMENT-RESPONSE headers (v2)
 *  - SIWx wallet-based sessions (pay once, then access via wallet sig)
 *  - Payment agreement extension (subscription terms in 402 response)
 *  - Pre-settled smart account payments (X-Payment-Tx header bypass)
 *
 *  The root GET / serves the off-chain catalog (free, no payment required).
 *  When httpServer is null, paid routes return 503 (graceful degradation).
 *
 *  When `storage` is provided, two additional wirings activate:
 *  - F4: `X-Access-Grant: session | agreement` response header on SIWx grants
 *    without fresh settlement (accessGrantHeaderMiddleware).
 *  - N5: pre-settled payments (X-Payment-Tx) are recorded into the SIWx storage
 *    so repeat requests with a wallet signature don't re-settle (double-charge fix).
 *  Storage omitted → byte-identical previous behavior.
