Two fixes:
1. Added https://homarr-labs.github.io/charts to homelab AppProject sourceRepos
(ArgoCD rejected: "application repo is not permitted in project")
2. Removed env array from homarr-values.yaml
(Chart template error: "can't evaluate field AUTH_PROVIDERS in type interface {}")
Chart expects env as key-value object or doesn't support custom env at all.
Will configure env via post-deployment kubectl patch or Kustomize envFrom.
Allows Homarr Application to sync successfully.
