chemavxandClaude Opus 4.8 33f429e412 monitoring: cierra el formulario local de Grafana 
Con el SSO ya funcionando (379af6d), a la web sólo se entra por Authentik.
Ayer se dejó abierto a propósito porque el SSO acababa de estar 15 días roto en
silencio y no quería quedarme sin puerta; hoy, verificado que funciona, se
cierra.

Lo que NO cierra, y es lo que importa: la auth básica de la API sigue abierta.
De ella cuelgan los dos sidecars —que es exactamente lo que se rompió mudo el
21 y dejó de recargar dashboards y datasources— y la puerta de emergencia con
la contraseña del secret grafana-admin.

Sí desaparece la otra: el POST /login pasa a devolver 400. Comprobado antes y
después, porque era la salida que uno supondría disponible y ya no lo está.
El procedimiento de rescate queda escrito junto al valor: la API con
grafana-admin, y disable_login_form: false + helm upgrade para recuperar el
formulario en un minuto.

Verificado: SSO entra como akadmin; la auth básica entra como admin;
disableLoginForm=true y authProxyEnabled=true en /api/frontend/settings; desde
fuera sigue el 302 a Authentik; y los DOS sidecars probados con ConfigMaps
reales, con 200 OK y el dashboard de prueba llegando de verdad a Grafana (y
desapareciendo al retirar el ConfigMap). 0 errores en el arranque.
