## Summary by CodeRabbit
* **New Features**
* External IPs count now shown in the Tenant application Details tab — a
left-column item displays the number of external IPs for LoadBalancer
services.
* Application status now exposes an External IPs Count metric for Tenant
applications, so UI and APIs can surface the number of LoadBalancer
external IPs without changing other behaviors.
<sub>✏️ Tip: You can customize this high-level summary in your review
