Detect and offer to format empty (no filesystem) partitions on the system
disk. Adds IsSystemPartition() for granular per-partition safety checks
instead of blocking the entire system disk. Init wizard shows formatable
partitions with appropriate warnings. Add felhotest demo node to docs.

rename() fails with EBUSY on Docker bind-mounted files. Add safeWriteFile()
helper that tries atomic rename first, falls back to direct write. Fixes
both init wizard and attach wizard fstab operations.

Docker always creates a fresh tmpfs at /dev, silently dropping any
/dev:/dev bind mount. Block devices must be accessed via /host-dev
where the host /dev is actually mounted.
Changes:
- docker-compose.yml: /dev:/dev → /dev:/host-dev:rw
- safety.go: add HostDevPath constant + HostDevicePath() helper
- format_linux.go: all device ops (stat, sfdisk, partprobe, mkfs.ext4,
blkid) use HostDevicePath() to resolve /dev/sdb → /host-dev/sdb
- safety_linux.go: IsSystemDisk() stats device via /host-dev
- scan_linux.go: enrichWithBlkid() probes each partition individually
via /host-dev/sdXN instead of batch blkid -o export (which can't
find devices when /dev is Docker's minimal tmpfs)
Fixes "stat /dev/sdb: no such file or directory" in FormatAndMount.

- 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
