Wise bank import does not populate payee name

[russss]

Payee name was showing as "None" on the bank payment screen - these accounts were auto-populated by the Wise import function:

Additionally, the payment config screen (/admin/payment-config) does not show this problem.

We should:

• Import the payee name (presumably this is possible) or require manual entry
• Show the payee name on the payment config screen
• Prevent a bank account from being activated on the payment config screen if it doesn't have a payee name.
• Throw an exception in the payment flow if the payee name or any other required payment details are not present.

No issue for 2024, I've manually populated these in production.

Ok; we're pulling the incorrect field names here; the title field that we attempt to read from is from the new-format account-details API; previously the relevant field was, I think, named accountHolderName in the (now-deprecated) borderless-accounts API.

At the time of writing, the Account Details API isn't yet supported in pywisetransfer.

Closing - I believe this was fixed by #1329.
