EAS GraphQL API wraps response in data while metadata doesn't.

• Update utils/fetchAttestations with the wrapping data (r.data.data...)

  	return fetch<{ attestations: AttestationWithMetadata[] }>(eas.url, {
  	method: "POST",
  	body: JSON.stringify({
  	query: AttestationsQuery,
  	variables: {
  	...filter,
  	where: {
  	schemaId: { in: schema },
  	revoked: { equals: false },
  	time: { gte: startsAt },
  	...filter?.where,
  	},
  	},
  	}),
  	}).then((r) => r.data?.attestations.map(parseAttestation));

• Update utils/fetch to return (await r.json()) as T
