Introduces a `before-starting` hook that creates a `CAN_INSTALL` file, signaling Nextcloud to proceed with its installation process.
Configures ArgoCD to ignore differences in `batch/Job` resources' `spec.selector` and `spec.template.metadata.labels`. This prevents spurious out-of-sync states caused by Kubernetes mutating these fields on job creation, improving application synchronization stability.
