Grafana sign-in failed with "Failed to get token from provider". The deployed
client secret no longer matched, because _ensure_oidc_apps called
_generate_client_secret for every app on every run, and ZITADEL stores exactly one
client secret per app: each call replaced the previous value and invalidated every
deployed copy.
Two changes:
1. Generate a secret only when the app is created. For an app that already exists,
reuse the value from state.json, because the API cannot read a secret back.
2. Re-encrypt grafana-oidc-secrets.enc.yaml with the live secret, so Grafana's
token exchange succeeds again.
Verified with the introspection endpoint:
old deployed secret -> {"error":"unauthorized_client"}
new secret -> {"active":false} (credentials accepted)
