i am using ingress and my configuration looks like
extraEnvVars:
- name: CLOUDBEAVER_ROOT_URI
value: "/database/"

- name: CLOUDBEAVER_SERVICE_URI
value: "/database/api/"

### Steps to reproduce

_No response_

### Expected/Desired Behavior

It should work after this configuration as well.

### CloudBeaver Version

Cloudbeaver community 26.1.2

### Additional context

_No response_

Start by checking how the ingress routes /database/api/gql and how CLOUDBEAVER_ROOT_URI and CLOUDBEAVER_SERVICE_URI are applied to the GraphQL request. Reproduce the serverConfig request through the configured /database/ path; done means the POST reaches the GraphQL endpoint without a 405 response.
