The training API client sends X-Tenant-ID: "default" which the proxy was
forwarding as-is, causing the backend to return 0 results. Now both proxies
validate that tenant/user IDs match UUID format before forwarding, falling
back to the configured defaults.

Both academy and training proxy routes now set default identity headers
so the Go backend RBAC middleware can set the tenant context. Without
these defaults, the browser doesn't send X-User-ID and modules/courses
return empty.
