Sign EIP-712 typed data

This endpoint authorizes that the caller has signing permissions for a specified managed key and signs the message with it.

The optional includeNodeProof flag is used to additionally sign the resulting signature with the node's own secp256k1 key, allowing for on-chain verification.
