Relay Submit Endpoint

Step 2: relay the signature. The Facilitator pays; the rater is the author.

The feedback parameters are passed through rather than re-derived: the Facilitator rebuilds the registry calldata from them and demands the signature cover exactly that, so altering one in flight breaks verification.

That property protects the CONTENT of the rating, not the RIGHT to write it. The rater signs its own digest, and chain_id, delegate and the account nonce are all public — so nothing stops someone from building a valid signature without ever calling /relay/prepare, and posting it here for a task they had nothing to do with. Which is why this endpoint runs the same checks as prepare instead of trusting that prepare ran.
