… backups https://hopsworks.atlassian.net/browse/HWORKS-2971 Document Trino authentication in the disaster-recovery backup section: the password and group files and the admin and monitoring credentials are labelled and captured by the k8s-backups-main Velero schedule, Hopsworks rebuilds the password and group files from restored RonDB state after a restore, and the internal shared secret is deliberately not backed up. Add the operator notes on protecting the backup store (it holds usable admin credentials) and the ArgoCD ignoreDifferences requirement for self-healing installs.

Pull request overview
This PR updates the Disaster Recovery documentation to explicitly cover how Trino authentication data is handled during Velero-backed backup/restore, including post-restore behavior and operator guidance for secure handling and ArgoCD-managed clusters.
Changes:
- Expands the “Kubernetes objects” backup scope description to include Trino authentication artifacts.
- Adds a new “Trino authentication” section describing what is backed up, what is rebuilt after restore, and what is intentionally not backed up.
- Adds operator-facing warning/note callouts for credential exposure in backups and ArgoCD self-healing considerations.

… backups https://hopsworks.atlassian.net/browse/HWORKS-2971 Add an operator note to the Trino authentication DR section: the automatic recovery holds only for backups taken after this feature was deployed. A pre-upgrade backup does not contain the Trino Secrets (they were not yet labelled for the k8s-backups-main schedule), and an existing cluster first has such a backup only after its next backup cycle. Restoring an older backup still recovers all RonDB-derived authentication via the reconciliation, but not the admin/monitoring credential entries, which are re-rendered from chart values on a fresh install, so out-of-band rotations are lost and Prometheus may need its Trino monitoring credentials re-aligned.
