feat(catalog): prevent and repair Arcturus emulator data errors

Block invalid catalog_items writes at the API level (points currency
allowlist, non-negative prices, positive amount, limited stack >= sold
count, unique sibling order numbers) and auto-assign unique order numbers
on bulk create. Add a catalog-maintenance scan + transactional repair that
fixes pre-existing rows: resets unsupported points_type, clamps negative
costs, sets amount to 1, raises limited_stack, renumbers duplicate orders
and deletes offers with missing page/item references. Surface the issue
count and a fix button in the admin maintenance panel.

Also: add enabled/retired flag to clone sources, classify poster and
currency furniture in item-kind, and remove the obsolete update-Nitrov3.sh.
