URL: https://github.com/apache/superset/pull/38513#issuecomment-4051282360
## **Sequence Diagram**
This PR fixes legacy chart exports by building relative explore URLs before
submitting the export request, preventing double-host request failures. It also
adds legacy xlsx handling on the backend with shared export permission checks
for both csv and xlsx.
