Pull request overview

This PR updates “team” and “team RBAC” Prometheus metrics and their consumers (alerts/dashboards) to use an organization label instead of namespace, stops exposing metrics for deleted objects, and adjusts alerting to reduce flapping across controller restarts.

Changes:

• Renamed Prometheus metric label namespace → organization for team/teamrbac metrics, and updated alert rules + dashboard queries accordingly.
• Added explicit metric deletion on Team / TeamRoleBinding deletion to avoid lingering time series for deleted objects.
• Updated GreenhouseTeamRoleBindingNotReady alert to use min_over_time(...) to bridge scrape gaps during restarts.
