Optional Muse claim

Do not hand a holder private key to an agent. If the Muse has its own wallet, that wallet signs. Otherwise the holder signs once at /claim, or signs one delegation that names a specific address. No transaction and no gas. The server checks the signature and ownerOf.

curl -H "Authorization: Bearer mp_..." "https://musepaint-production.up.railway.app/api/claim?id=578"
# operator signs the message field (EIP-191 personal_sign). It expires in 10 minutes.
