[MIG] internal_transfer_with_agreed_amount: Migration to 17.0 t#71297

[CLaurelB]

Changelog:

• Replace attrs with an expression for the invisible attribute in the view.
• Add payment amount and currency update after the move is set to draft. This is because the undoing of the reconciliation triggers an update on the payment, and the amount gets updated to the previous agreed amount along with its corresponding currency. This happens when the agreed amount is edited.
• Enable the euro currency in the test since it's required for multicurrency transfers.
• Fix ambiguous variable name.
