librelad 52e4280a67 feat(webui): add 'Migrate' tab — restore an app from another LibrePortal
Phase 1 of the migration-system refresh. Surfaces Phase 0's kernel
(libreportal restore migrate ...) as a WebUI flow so users don't have
to drop to the CLI to pull an app from a peer's backups.

backend / data generator:
  scripts/webui/data/generators/backup/webui_backup_migrate.sh
    Walks every enabled backup location, lists every (other_host, app)
    pair with snapshot count + latest id/date, and emits a single
    destination summary block (installed apps, running apps, disk free)
    so the frontend can compute collisions and warnings without per-row
    API round-trips. Filters out our own hostname — we don't migrate to
    ourselves. Output: data/backup/generated/migrate.json.
    Hooked into the standard webuiLibrePortalUpdate refresh pipeline,
    so 'libreportal regen webui' (and the periodic task-processor poll)
    keep it fresh on their own.

frontend:
  - New 'Migrate' sidebar tab on /backup, sits between Locations and
    Configuration. Path-based URL: /backup/migrate.
  - Per-source-host cards listing every available app, with snapshot
    count + relative-time hint, collision dot when the app is already
    installed here, and per-app + per-host migrate buttons.
  - Confirm modal with two checkboxes matching the kernel's defaults:
      [✓] Back up the destination's existing copy first   (pre-migrate
          backup; auto-disabled when there's nothing to back up)
      [✓] Rewrite host-bound URLs to this host             (URL rewrite
          — uncheck only to keep source hostnames)
    On confirm, runs 'libreportal restore migrate app/system …' via the
    task system; opt-out checkboxes append --no-pre-backup / --keep-urls
    only when the user un-ticks, matching the kernel's default-on flags.
  - Empty state when no other hosts have visible backups, explaining
    the shared-backup-location prerequisite.

The CLI dispatcher hooks (Phase 0) wire restore migrate app/system to
migrateApplyApp/migrateApplySystem, so the WebUI gets pre-backup safety,
URL rewrite, and structured progress (when --json-progress is set; not
needed here yet — the task system's log tail is enough for v1).
