The Ingress already handles the /btpxpress path prefix with rewrite-target,
so the backend should serve requests directly without a root-path.
This fixes the 404 errors when accessing endpoints like:
- https://api.lions.dev/btpxpress/q/health
- https://api.lions.dev/btpxpress/api/*
Before: Backend expected /btpxpress/q/health (due to root-path)
After: Backend serves /q/health (Ingress rewrites /btpxpress/... to /...)
