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.

Add structured operational logging at INFO, WARN, and ERROR levels to
every controller module. Standardize custom prefixes ([GEO], [SCHED],
[SYNC]) to use [INFO/WARN/ERROR] [module] format. Fix misleveled logs
(WARN->ERROR for data loss scenarios, WARN->INFO for routine operations).

Add detailed [DEBUG] logging to every controller module when
logging.level is set to "debug". Each module with stateful debug
uses SetDebug(bool) wired from main.go. Covers stacks, backup,
cloudflare, integrations, system, monitor, settings, scheduler,
web handlers, storage, metrics, API, selfupdate, and assets.
Also includes the app export/import (.fab bundles) feature from
v0.32.0 and its debug page integration.

Phase 1: Deprecate restic as Tier 2 method (rsync only), auto-migrate on startup
Phase 2: Enhanced per-app migration with backup awareness, DB dump copy, auto-cleanup
Phase 3: Full drive migration with decommissioned state, rollback support, wizard UI
Phase 4: Hub report includes decommissioned drive state

CreateDirectory now returns an error when the folder already exists
instead of silently succeeding. JS validates folder name format
(alphanumeric + underscore, max 32 chars) before sending the request.

After an interrupted attach wizard, the raw mount stays behind,
causing the device to appear as "mounted" in scan results. Now the
scan button calls cancel first, which unmounts any stale raw mounts
that have no bind mount in fstab.

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.

New Settings wizard to attach drives with existing filesystems without
formatting. Mounts partition at staging path, lets user browse and pick
a subfolder, then bind-mounts it at /mnt/<name> with fstab entries.

Bug 1 (sfdisk): Add wipefs before sfdisk; change partition type from
,,,L (unsupported GPT shorthand) to ,, (default Linux GUID); add
--force --wipe always flags to handle existing partition tables.
Bug 2 (mount): Replace fstab-lookup mount with explicit device path:
mount -t ext4 -o defaults,noatime /host-dev/sdb1 /mnt/hdd_1
Container's /etc/fstab is Docker's auto-generated one, not the host's.
Bug 3 (mount propagation): Change /mnt volume to long-form bind with
propagation: rshared so mounts created inside container propagate to
the host. Requires mount --make-rshared /mnt on host before restart.
Safety: Use req.MountName (ASCII) for ext4 -L label (16-byte limit;
UTF-8 display label stays in settings.json). Add findmnt verification
after mount. Improve progress messages with command details.
Smart partition: In storageInitAPIHandler, if disk already has exactly
1 empty partition (no filesystem), skip wipefs+sfdisk and format the
existing partition directly.

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.

Bug 1: Inside container, lsblk reports container mount points not host's.
Parse /host-fstab (or /etc/fstab fallback) to find system partitions
(/, /boot, /boot/efi, swap), resolve UUIDs via blkid, and mark parent
disks as system — replaces unreliable mount-point string matching.
Bug 2: lsblk returns null fstype in containers (no udev cache). Run
blkid -o export after lsblk scan and enrich partitions with FSType,
UUID, and Label from direct device probing.
Fixes sda appearing as available disk and "nincs fájlrendszer" showing
for all partitions.

- 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
