Get Auth Message

Starts the 3-step authentication flow.

Step 1 (this endpoint): call GET /auth?account=<address> to receive a nonce-bound message, signing_payload, and server signature.

Step 2 (client-side): sign signing_payload with the account's Ethereum private key (EIP-191).

Step 3: submit message, signature, and server_signature to POST /auth to receive a JWT token.

curl -X GET "https://engine.cascade.cooking/auth?account=0xe1c03ec3bcf509b3e8e63abcd03edc661ffe6a78"
