Describe the problem

When running the DB Console behind a proxy that has a different base URL, it's necessary for existing XHR requests to be made relative to that base path that's being proxied to the cluster (say: http://example.com/my-cluster/prod-cluster/...). This ensures that all requests in addition to the initial asset requests can complete successfully.

It appears that the uiconfig and api/v2 routes were configured as absolute instead of relative in the code, which breaks them when behind a proxy that changes the base URL.

To Reproduce
Run DB Console and CRDB behind an HTTP proxy with a base URL different from /.

Observe:

and

which tells us that /uiconfig loaded incorrectly
and

which tells us that SQL-over-HTTP endpoint requests cannot be loaded.

Expected behavior
DB Console runs as expected and pages load successfully without errors.

Environment:

• CockroachDB version: 22.2.0-beta5
• Client app: DB Console
