Pull request overview

This PR adds support for “offline” Atlas Cloud tokens by persisting Atlas CLI state per resource (via a configurable data directory) and performing an explicit atlas login --grant-only when a token is provided.

Changes:

• Extend the Atlas CLI client factory to accept cloud config + a per-resource “home” path and set HOME/ATLAS_TOKEN for Atlas CLI executions.
• Perform cli.Login(...GrantOnly: true) during schema/migration reconciliation and lint flows when a Cloud token is present.
• Add PVC-backed persistence wiring (PVC + DATA_DIR env + mount) to kustomize manager manifest and Helm chart; bump ariga.io/atlas dependency.
