v0.15.5: Disaster recovery — Hub-based infra backup, auto-mount, restore UI

Complete DR implementation (TASK2.md Phases 1-4): - Hub infra-backup push/pull endpoints (controller.yaml, disk layout, stacks) - Fresh-deployment detection pulls config from Hub, auto-mounts drives by UUID - Full-page restore UI with drive status, app table, sequential restore - docker-setup.sh shows DR instructions when customer_id is configured New files: disk_layout.go, restore_scan.go, restore_app_linux.go, restore_drives_linux.go, infra_backup.go, infra_pull.go, handler_restore.go, restore.html Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
