Subject: [PATCH] Show current catalog price and price-change nudge on
 inventory detail
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Surfaces the synced CatalogReferencePrice on the inventory detail pricing card:
"Current Catalog Price" (the price quotes use), with an info popover clarifying
it doesn't affect Unit Cost or stock value, an "Updated <date>" line, and a
badge nudging when it differs from what they last paid ("Price up/down from
$X last paid"). Adds CatalogReferencePrice/CatalogPriceUpdatedAt to
InventoryItemDto (auto-mapped). Display only — no pricing/accounting impact.
