fix(catalog): make the Builder Club catalog read and write its own offers

The previous commit taught bulk editing and delete-with-restore about the BC
catalog. Neither actually worked, and one of them was destructive.

`catalog_items_bc` has six columns: id, item_ids, page_id, catalog_name,
order_number, extradata. There is no price, points, currency, offer_id, limit or
membership column on it. The bulk path read and wrote columns that do not
exist, and the UPDATE was aimed at catalog_items while the SELECT came from
catalog_items_bc — so a BC category move wrote into the normal catalog. Two
tests now pin that pairing: reads and writes have to stay in the same table.

Underneath it the BC table was never being read at all. The inline editor
fetched `/api/admin/catalog/items?pageId=N` without the catalog, so opening a BC
category showed the normal catalog's offers, and the route selected BC rows
directly instead of going through the loader, skipping the furni enrichment the
table needs to render anything but a bare caption. Both catalogs now take the
same path, and the catalog is in the fetch callback's dependencies — without
that, a switch keeps reading the previous catalog's rows through a stale
closure.

Because a BC offer has no price, the editor no longer offers one. The server
refuses price, points and currency changes with a readable message instead of
letting them reach the database as an unknown-column error, and a BC bulk edit
is what it can actually be: a category move.

BC deletions also went through a bare DELETE, which made them the one catalog
mutation with no way back. They now keep their rows and hand back a restoreId
like the normal ones. The catalog is recorded in the audit target rather than
in the payload, so a restore can never put a BC row into the normal offers
table.
