mock.shop_amazon_listing_counts is a recursive view that computes a
running inventory count: starting from the listing's base count in
mock.shop_amazon_listings, it walks mock.raw_shop_events in order,
applying each event as a delta (sale/refund) or an absolute reset
(inventory-reset), per mock.shop_amazon_listing_event_sequence's
interpretation of each row's JSON payload. This is the first test to
exercise that view directly rather than just the Go code around it.
Fixture uses the real SaveNewMockSale/SaveNewMockRefund/
SaveNewMockInventoryReset methods - the same entry points the
simulate-sale/refund/inventory UI uses - rather than hand-rolling the
JSON payload shape, so the test tracks the real payload contract.
Covers the full running-count sequence (base -> sale -> refund ->
reset), the unknown-listing ErrNotFound case, and
GetListingCountsReport's MaxCount/MinCount over that sequence.

Covers the happy path (ordering by event_timestamp DESC/event_id ASC,
Platform/ShopID fields, RawPayload round-tripping through jsonb), the
empty-shop case, and the unknown-shop ErrNotFound case (via the
accts.GetMockShop check GetRawShopEvents does before querying).
setupAmazonMockShop creates a real account + Amazon mock shop via the
same Store methods the app uses (CreateAccount, CreateMockShop) and
registers cleanup in FK-safe order.
GetListingCountsOverTime/GetListingCountsReport coverage is a separate,
larger task (needs a listing plus count-changing history feeding a DB
view) - not done here.
