The Authentik client for ArgoCD is now public (the iOS app can't hold
a secret), so Authentik no longer enforces client_secret on token
exchange. PKCE replaces that as the protection against
authorization-code interception.
- Add `enablePKCEAuthentication: true` to the `oidc.config` block in
`argocd-cm-patch.yaml`
- Note why PKCE is needed now that the client is public
