Bug 22113: Add price formatting on item lost report

The item lost report displays the price and replacement
price for lost items. With the patch they will display
according to the CurrencyFormat system preference.

To test:
- Mark 1 or more items lost
- Make sure that replacement cost and purchase price are set
- Go to Reports > Items lost
- Search for your lost items
- Verify price and replacement price display
- Apply patch and toggle CurrencyFormat to different settings
- Refresh lost items report
- Verify prices are always displayed according to syspref setting
