Make Product properties optional and improve safety

Updated the `Product` type in `product-service.ts` to make `price`, `colors`, and `priceSale` optional. Removed hardcoded values from the `getProducts` function, allowing for more flexible product creation. Enhanced the `ProductItem` component to safely access the `colors` property using optional chaining, defaulting to an empty array if undefined.
