GAPS 2D scanner -- parse text stream on server

[CarlosNZ]

Suggested implementation:

• Front end current sends asset ID (assetById query). Planning to change this to a new Gql endpoint which just sends the raw scanned data as parameter. The data could be either an ID (from QR code) or a GS1-formatted string
• Server decides which type of input it is handles accordingly:
  • If an ID, return Structured error if it doesn't exist, and returns the asset data as normal if it does
  • If it's a GS1 string, server will parse the text into the correct fields. It will then perform a search by serial number. If that serial number exists, it'll return the asset data as normal. If it doesn't exist, it will return the parsed asset data, with an extra field assetExists set to false
• If the front end gets a returned object with assetExists === false, it will then ask the user (via confirmation dialog) whether they want to create the asset.
• If the confirm "Yes", the asset will be created using the standard insertAsset GraphQL node, using the previously returned data as the input patch.

Great. I think we can use enum to specify if it's id or GS1 string being passed as the first input.

assetExists === false

I think it's better as a union result variant (one variant for found one variant for not found).
