fix(revenuecat): address PR review feedback

- create_purchase: wrap JSON.parse(attributes) with try/catch and clear error
- update_subscriber_attributes: drop subscriber output (endpoint returns
  empty body) and guard JSON.parse on attributes
- grant_entitlement: throw when both duration and endTimeMs are provided,
  matching defer_google_subscription behavior
