feat(inventory): add multi-country origin tracking

- Added `originCountries` field to `InventoryItem` model for multi-country origin support
- Updated `CreateInventoryDto` and `UpdateInventoryDto` with `originCountries` array field
- Modified `InventoryService` to handle `originCountries` in create and update operations
- Added `origin` field to `FlyerImportItem` response type for consistency
- Added `categoryId` field to `ParsedReceiptItem` DTO for improved receipt parsing
- Created database migration `20260524_add_origin_countries` for schema changes
