Claim Distribution

Returns an EIP-712 signature for one distribution row so the user can claim tokens from the distribution contract. Idempotent — the same (user, distribution, nonce) always yields the same signature.

POST /points/claim/:distribution_id

Auth: Authorization: Bearer <JWT> from the EIP-712 login. API keys are not accepted.
