fix(cashier): tag GL-entry denomination to the vault, show both voucher legs

- Transaction Entry's manual GL-entry screen was recording its denomination
  breakdown against whichever GL account the teller selected, not the vault
  account whose physical notes actually moved -- resolve and use the Cash
  Vault GL's own code/name dynamically instead
- Closing Cash Report's GL Entries table showed only the one account its
  denomination row knew about; now shows both the debit and credit account
  of each voucher (backend now returns debitParty/creditParty), matching
  what My Vouchers already shows for the same entries
