Multi-currency Bank Accounts (one account holding several currencies in
parallel) exist with some western banks like Revolut/Wise, but in AZ the
convention is one Bank Account per currency. The toggle was extra noise
on the File Format tab for every user.
Kept the field and the underlying parse/import logic intact (hidden=1
only). Removing the hidden flag re-exposes it if a real multi-currency
case ever shows up.
