feat(catalog): add scripts/catalog-sync.ts CLI + interactive menu

Updating the catalog was only possible from the admin "Catalog audit" page,
which streams `runCatalogAudit` over SSE and always compares against every
enabled clone source. This adds the same engine to the terminal so it can be run
by hand or from cron:

- `scripts/catalog-sync.ts` — CLI driver around `runCatalogAudit`. Prints the
  live progress, the per-source "on the source but not in this hotel" counts and
  a summary block; generated catalog SQL is saved to
  `storage/catalog-sync/*.sql` (gitignored). Supports `--list-sources`,
  `--sources=<a,b>`, `--icons`, `--nitros`, `--furnidata`, `--structure`,
  `--check-ids`, `--sql`, `--apply-sql`, `--organize-sql`, `--all`, `--json` and
  `--fail-on-errors`.
- `scripts/catalog-sync.sh` — interactive menu (`pnpm catalog:sync`). Lists the
  configured sources (so the menu always matches `clone_sources`), lets Habbo
  (COM) be taken with Enter, and offers audit-only through full repair +
  applying the catalog SQL, each with a distinct confirmation. With no arguments
  it needs a terminal; with any flag it passes straight through to the CLI.
- `runCatalogAudit` gains `sourceIds` to restrict which sites are compared;
  omitting it keeps the previous "compare against everything enabled" behaviour.

An audit writes nothing, and `--apply-sql` is the only flag that changes the
catalog. Verified against the live DB: 16370 items_base rows, 16479 catalog
items, 2871 Habbo (COM) entries missing from this hotel.
