feat(catalog-sync): add import, reconcile, sprite-id and offer steps

The CLI could audit and repair what already existed, but adding furniture
present at a source was still only possible from the admin UI item by item. The
repo already ships every piece of that pipeline, so wire them together as
further steps of the same run:

- `--import-new` imports furniture the compared source has and this hotel lacks.
  It reuses `getClonableClassnames` for the diff and `cloneSingleFurni` per item,
  which downloads the icon and the bundle (sources serve `.nitro`, stored as
  `.hab`), appends the furnidata entry with `deferFurniData` and creates the
  catalog page plus the offer itself. Deferred entries are written in one
  `appendFurniEntriesBulk` call, so 26000 items cost one JSON write, not one per
  item. `--only`, `--limit` and `--concurrency` narrow/tune it, failures are
  isolated per item and never abort the run.
- `--reconcile`, `--fix-sprite-ids` and `--rebuild-offers` run the existing
  `reconcileFurniDataWithItemsBase`, `verifyAndFixSpriteIds` and
  `rebuildCatalogOfferIds` passes — the post-import consistency work.
- `--align-ids` and `--rename-bundles` delegate to the existing standalone
  scripts; both only report until `--apply` is given, matching their own
  contracts.
- The menu grows options 6-8 plus a dry run, each with its own confirmation.

`--everything` turns on every repair + import step but deliberately leaves the
destructive ones off. A live dry run against Wibbo listed 26593 items on the
source that this hotel does not have, and Habbo (COM) reported 2871.
