fix: propagate health field to tray for consistent connected count
The tray was showing incorrect connected counts (8/15) compared to CLI (13 healthy) because the health field was not being propagated through the API client layer. Changes: - Add HealthStatus struct and Health field to tray API client - Extract health from JSON response in GetServers() - Include health in adapter GetAllServers() output map - Add extractHealthLevel() helper to managers.go - Add debug logging to trace health extraction - Add validation script (scripts/validate-health-api.sh) - Add tests for health propagation and consistency Spec 013: Health is the single source of truth for server status.
