      Wallet-authenticated maker assignments. The signed session must match both
       configured maker user and application. Owner IDs are process fences, never auth.
       Only wallet sessions are supported; delegated-agent sessions receive 403.

       - a user has one parent margin account per application scope
       - opening orders create or reuse isolated position buckets under that parent

      Current public isolated-margin semantics:
       - positions link to a parent margin account and, when applicable, a bucket id
       - opening orders create or reuse isolated position buckets under the parent
       - users can open another isolated position by reusing the parent account with a different market bucket

        Ed25519 session-key request signing. Every authenticated request carries
        three headers: `X-Monaco-PublicKey` (64-char lowercase-hex session
        public key), `X-Monaco-Timestamp` (Unix milliseconds, within 30s of
        server time), and `X-Monaco-Signature` (hex ed25519 signature). The
        signature is over `METHOD\npath?query\ntimestamp_ms\nSHA256_hex(body)`,
        where the body hash is the SHA-256 of the empty byte string when there
        is no body. Obtain the session keypair from `POST
        /api/v1/auth/challenge` followed by `POST /api/v1/auth/verify`.

        RFC 9421 Ed25519 session-key request signatures. Send Signature-Input,
        Signature, and Content-Digest together; never combine them with
        X-Monaco-* credentials. The monaco signature covers @method, @path,
        @query, and content-digest in that order, with created (Unix seconds
        within 30s of server time), keyid (registered lowercase-hex session
        public key), and alg=ed25519 parameters. Content-Digest uses RFC 9530
        sha-256 over the exact body bytes, including the empty body. Query
        coverage retains ordering and percent encoding. Timestamp freshness does
        not reject repeated identical requests; use endpoint idempotency where
        supported. Existing legacy signing remains supported during server-first
        migration; SDK RFC 9421 signing is opt-in. See
        https://docs.0xmonaco.com/reference/http-message-signatures for the
        complete profile and trust model.
