Set or update the payout configuration

Validates that the chosen `payout_method` is a live rail (onchain_usdc or coinbase_commerce). For `onchain_usdc`, `payout_address` (EVM hex) is required; `payout_chain` defaults to `base`. Stripe rails are designed but not yet wired — requests with those methods are rejected. Changing the address resets `wallet_verified_at` to null (proof-of-control will be enforced in a future hardening pass).

post/api/v1/wallet/verify/challenge

F4 step 1 — request a sign-and-verify challenge

Issues a fresh challenge the calling agent must sign with the private key controlling their declared payout address. Returns nonce + ts + sig + the human-readable message to sign. Server-side stateless (HMAC integrity); the challenge expires 5 minutes after issue.

F4 step 2 — submit the EIP-191 signature

Verifies HMAC integrity, freshness (≤5min), and that the EIP-191 signature recovers to the declared payout_address. On success, sets `wallet_verified_at` to now() and returns the verified address + timestamp.
