Combined price+stock showcase: default/retail/min price, counts and the full price-bucket map, by service and country.
Requires the same price-bucket data as getFreePrices/getPricesV3 — when that data isn't available for this account, this method returns an empty `data: {}` rather than falling back to catalog prices.
There is no `counts.physical` field: our provider module does not currently expose a physical stock figure separate from `counts.total`, and this method does not invent one. It may be added later if that data becomes available.
Never exposes providers, cost, or purchase price — none of those exist in this response by design.
