Move all 8 Authentik OIDC client_secrets out of plaintext git

Completes the 'make the repo proper' cleanup from earlier this session -
these were flagged but deliberately not touched in 185e9c2 given the
blast radius (live SSO for 8 apps). User confirmed: fix all 8 now.

infrastructure/authentik/{argocd,gitlab,nextcloud,grafana,n8n,guacamole,
rancher,vault}-blueprint.yaml: converted from plain ConfigMap (client_secret
hardcoded) to ExternalSecret with a templated blueprint body
(client_secret: "{{ .clientSecret }}") pulling from Vault. Chart already
supports mounting blueprints from Secrets (blueprints.secrets, alongside
blueprints.configMaps) - infrastructure/authentik/values.yaml updated to
route these 8 there instead.

For argocd/nextcloud/n8n/guacamole/rancher: Vault already had the matching
value at secret/<app>-oauth (the APP side was already Vault-backed via its
own ExternalSecret) - the blueprint was the only remaining plaintext copy.

For gitlab/grafana/vault: Vault had no copy at all yet - created
secret/{gitlab,grafana,vault}-oauth with the EXISTING live values (not
rotated - these are the actual working credentials right now, rotating
would break login until every consumer is updated in lockstep, which is
out of scope for a cleanup pass). Also fixed the OTHER plaintext copies
that existed for these three specifically:
  - apps/gitlab/manifests/external-secret-oidc.yaml (new): replaces a
    manually kubectl-created, never-git-tracked gitlab-oidc-secret.
  - infrastructure/grafana/manifests/grafana-oauth-secret.yaml: was a
    plain Secret whose own comment said 'hardcoded from blueprint'.
  - infrastructure/vault/manifests/vault-init-{configmap,job}.yaml: this
    one COULDN'T be converted to the same ExternalSecret-from-Vault
    pattern - it's the PostSync Job that grants ESO's own Kubernetes-auth
    role in Vault, so ESO can't yet authenticate to pull anything from
    Vault at the point this script runs (genuinely circular). Sourced
    from a new vault-oidc-bootstrap Secret instead - created once
    manually (kubectl, not git, matching how Vault's own root/unseal
    material is already handled), independent of the ESO pipeline.
