fix(grafana,alloy): remove editor panel from client dashboards and fix label replacement

- Strip embedded server-editor panel (id 90) from client drilldown dashboards to enforce read-only access for client viewers
- Fix dollar sign escaping in Alloy blackbox relabel configuration to prevent shell variable interpolation
- Client viewers can now only view dashboards without ability to modify server configurations
