Bug 22118: Format hold fee when placing holds in OPAC

When Koha charges for holds, a message with the fee is
shown before the patron places the hold. The amount needs
to be formatted according to CurrencyFormat system preference.

To test:
- Add a hold fee to your patron category
- Log into the OPAC
- Search for a record to place a hold on
- Click Place hold
- Verify there is a note showing about the hold fee
- Toggle CurrencyFormat and HoldFeeMode and verify
  that the formatting is always correct
