feat(services): add load balancing mode and active IPs to service view

- Introduced `lb_mode` to specify the load balancing strategy for services, supporting options like round robin, failover, and weighted.
- Added `active_ips` to track currently active IPs for each service, enhancing visibility into service health and configuration.
- Updated relevant components to display load balancing mode and active IPs, improving user experience and service management capabilities.
