GraphQL API endpoint ignores CORS origin restriction
Details
### Impact
The GraphQL API endpoint does not respect the `allowOrigin` server option and unconditionally allows cross-origin requests from any website. This bypasses origin restrictions that operators configure to control which websites can interact with the Parse Server API. The REST API correctly enforces the configured `allowOrigin` restriction.
### Patches
The GraphQL API endpoint now uses the same CORS middleware as the REST API, ensuring the `allowOrigin` and `allowHeaders` server options are consistently enforced across all endpoints.
### Workarounds
There is no known workaround other than upgrading.
