Improves JSON deserialization for product and stock picking models by using custom `fromJson` methods and explicit `JsonKey` mappings. This ensures robust parsing of fields like barcode, display name, and product IDs. Adds a new `ecart` getter to calculate the difference between requested and received quantities for stock moves. Updates the reception details page to display a list of products with their requested, received, and calculated difference quantities. Removes redundant JSON-RPC fields from the `stock.picking/web_read` API call.
