Bug 22120: Add price formattig to patron summary print

The patron summary print lists the replacement prices
and rental charges of items and totals them. With this
patch they will be formatted according to the
CurrencyFormat system preference.

To test:
- Find or create a patron with some checkouts
- Make sure some items have replacement price set
  and some have a rental charge
- "Print summary" from the account in staff
- Verify that charges and prices in the checkouts
  table are formatted correctly
- Toggle CurrencyFormat to different settings
