List price overrides (prix magasin) by store or by product
Lists store-scoped price overrides (prix magasin / prix spécifique) along ONE axis: pass ?store=<id> for every override authored in a store (the back-office authoring grid), or ?product=<id> for every store’s override of one sellable unit (the product price map — so a manager sees a produit’s price across the fleet in one call instead of fanning out per store). Provide EXACTLY ONE — a request with neither, or with both, 400s. Each override REPLACES the base catalogue price for its (store, sku) while active. For the resulting sellable price a till uses, read GET /products/:id/units?store=<id> instead.
Authorizations
Authorization: Bearer <token>. Accepts EITHER a Keycloak access token (scopes-in-token) OR an opaque POS session token; both resolve to the same pos.* scope vocabulary the route guards enforce.
