Subject: [PATCH] Add unit price and extended price columns to project BOM
 table

Adds two optional columns to the project BOM datatable (hidden by
default, toggleable via column visibility):

- **Price**: unit price for the BOM entry in the base currency,
  looked up via PricedetailHelper. For parts whose BOM quantity falls
  below the minimum order amount the minimum order amount is used for
  the price tier lookup so that a price is always returned.
- **Extended Price**: unit price multiplied by the BOM quantity.

Prices are rendered via MoneyFormatter (locale-aware, with currency
symbol). Both columns round up to 2 decimal places to avoid displaying
0.00 for very small prices.
