Add forte-cli public device-code Keycloak client

Add a shared public client `forte-cli` to the `forte` realm so downloaded
skills (forte-drop first) can do RFC 8628 device-code login through the
Auth Sidecar. Today no client in the realm has the device grant enabled,
so the flow cannot start.

Client (inline in forte-realm.json, imported verbatim by keycloak-config-cli):
- publicClient: true, standardFlowEnabled: false,
  directAccessGrantsEnabled: false
- attributes: oauth2.device.authorization.grant.enabled=true
- no secret, no redirectUris/webOrigins, no k8s.secret.sync

It has to go in the realm JSON because the self-service registrar
hardcodes publicClient:false/standardFlowEnabled:true and drops
attributes. Also add forte-cli to the cleanup CronJob's protected list
(belt-and-braces; it does not match the UUID pattern anyway).

Additive only: gitea/grafana/argocd and all other realm settings are
unchanged. Keycloak is deployed only via the upc-dev overlay, which
inherits base values, so this lands on id.forteapps.net.
