`purchase` listed a shop's offers with no ordering while `getShopView` orders
by `sortOrder`, so the two paths answered "which offer does this key mean" by
different rules, one of them at the database's discretion. Harmless today
because item and bag keys are disjoint, but not a difference worth keeping.
The faction lookup behind requirement labels also read every faction while the
condition engine only matches enabled ones, so a gate on a disabled faction
would have shown that faction's name next to a requirement the engine treats
as unmeetable.
