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.
Detect badges by items_base.type='b' (authoritative, album gifs as
fallback), recognize pet/animals (a0 pet<N>, pet<N> interaction) and
system items (effects, bots, sticky notes), and resolve asset names for
dot/star classname variants so the audit no longer floods with false
missing nitro/icon errors and repair skips non-furni items.
