Display encumbered value on POL for orders made in currency other than system currency

Overview: Currency setting on order record is currently ignored. When changing the currency setting for POL in cost accordion it should ensure that we are capturing cost and fund distribution information in that currency so the backend can convert it to the default currency when making an encumbrance.

Acceptance criteria:
Given the user selects a currency other than the default currency
When saving the POL
Then Cost information is shown in the correct format with the currency symbol (Including the Fund distribution amount)

Given the user selects a currency other than the default currency
When saving the POL
Then Initial encumbrance value is shown in the correct format in the fund distribution table

Given the user selects a currency other than the default currency
When saving the POL
Then Current encumbrance value is shown in the correct format in the fund distribution table

Given the user selects a currency other than the default currency
When saving the POL
Then expended value is shown in the correct format in the fund distribution table This will be done in a different story as it should not come from the encumbrance
