admin 2fb2c6e1ae v0.11.0 — Phase C: Storage Init Wizard, Data Migration & Startup Fix
- Startup ping: fire heartbeat + health + hub report immediately on boot
  (5s delay after scheduler start, instead of waiting 5-15 min for first tick)

- Storage init wizard: new internal/storage/ package with disk scanning
  (lsblk -J), format+mount pipeline (sfdisk → mkfs.ext4 → blkid → fstab →
  mount → chown), safety guards (system disk detection, confirmation "FORMÁZÁS"),
  progress channel, auto-register in settings.json

- Data migration: MigrateAppData() with rsync --info=progress2 progress parsing,
  stop/rsync/update-config/start flow, rollback on failure, old data preserved

- New pages: /settings/storage/init (wizard), /stacks/{name}/migrate (migration)
- New API routes: /api/storage/{scan,init,init/status,migrate,migrate/status}
- Deploy page: storage info section for deployed apps (path, size, free, migrate link)
- Settings page: "Mozgatás" button per app in storage path details
- Container: privileged: true, /dev:/dev, /etc/fstab:/host-fstab, /run/udev:/run/udev:ro
- Dockerfile: add util-linux, e2fsprogs, rsync, parted for disk ops
