Lite: collector health status bar shows global errors instead of per-server #5
Description
The status bar text "Collectors: N erroring" reflects the global health summary across ALL monitored servers. If any offline server has erroring collectors, the status bar shows errors even when viewing a tab for a healthy, online server.
RemoteCollectorService.GetHealthSummary() aggregates all collector health entries without filtering by server. The status bar should either:
- Show health for the currently selected server tab
- Or separate online vs offline server errors
Related to #2 (overview parity) but different area of code.
