Fix: Correct Dockerfile HEALTHCHECK and Swagger UI URL for root-path configuration

- Fixed HEALTHCHECK to use /btpxpress/q/health/ready instead of /q/health/ready
- Added quarkus.swagger-ui.urls.default=/btpxpress/openapi for correct OpenAPI loading
- Ensures Swagger UI loads the spec from the correct path with root-path

These fixes ensure:
1. Docker health checks work correctly with quarkus.http.root-path=/btpxpress
2. Swagger UI correctly loads /btpxpress/openapi instead of /openapi
3. Pods are marked healthy by Kubernetes

Resolves the 404 error in Swagger UI when loading API definition.
