feat(container): add explicit data workflows and snapshot rollback (#193)

* feat(container): add explicit data workflows and snapshot rollback

Make container upgrades and recreation data-safe by adding explicit preserve, export, import, restore, and rollback flows across the backend, SDK, and web UI.

* fix(container): resolve go lint issues

Fix formatting and lint violations introduced by the container data workflow changes so the Go CI lint job passes cleanly.
