[Global Product Identifier] Barcode Scanner Search

[toupper]

Closes: #14332

Description

With this PR we add search by global unique identifier on top of SKU search after scanning a barcode (orders, Inventory). The logic is as follows:

• Scan a code (QR or barcode)
• Search by SKU
• If nothing is returned or fails, search by global unique identifier.

Steps to reproduce

1. Go to Products
2. Tap on a product
3. Tap on Inventory
4. Tap on the barcode button besides the GTIN field. Scan a barcode, and save the product.
5. Go to Orders
6. Scan that same barcode.
7. It should open the Create Order view with the above product added to the order.

Testing information

I also verified these cases:

• I verified that the scanning barcode that contains an SKU number keeps working fine.
• When the scanned code doesn't match either SKU or global unique identifier, we show an error message: "Product with Identifier <identifier> not found."
• When the product is not purchasable, we show the message: Product with Identifier is not purchasable."
