[API]: Add fee to transfers objects in GraphQL & REST

[edd]

Warning

Reopened as it is not possible in GraphQL to get the fee for an individual transfer

https://github.com/vegaprotocol/vega/blob/develop/datanode/gateway/graphql/schema.graphql#L718-L755

In GraphQL and REST, it is not possible to know what they fee paid for a transfer is. You can guess by looking at a network parameter, but that is unreliable for transfers in the past as the factor could have changed.

Changes

• A new field should represent the fee paid for a transfer
• The fee should be the value in the same asset as the transfer
• The fee should not be the fee factor, but the actual amount paid for the transfer

Tasks

• [API]: Add fee to transfers objects in GraphQL & REST #8056 (comment)
• Expose fee in GraphQL
• Expose fee in REST
• Either:
  • Recurring transfers should contain an array of fee objects containing the individual fees paid, and the date and time of each
  • Recurring transfers should contain a total of the fees paid to date

Reopened. In GraphQL, the fees are not exposed by the { transfer(id:"123"){...} } query. They are exposed by { transfersConnection(partyId:"456"){...} }, but the trransfersConnection query does not support selecting by ID

Tasks

• Add fees to query { transfer(){ ... } } } response in GraphQL
