fix(argocd): remove kustomize CMP plugin & use homelab project

- Remove non-existent kustomize CMP plugin (ArgoCD doesn't have it)
- Use standard built-in kustomize support
- Change project from 'poimen' to 'homelab' (homelab project exists)
- This allows poimen-workflows Application to actually sync
