Each report can define formats for each column. But currency formatting
was also applied to all columns that had "price" in the name. Removing
this automation gives us more control and we can decide for each case.
At the moment, the currency formatting in Excel spreadsheets is not
ideal and it's easier to keep it as number.
This PR introduces a visual regression as prices are not formatted as
nicely but the columns can be used in calculations.
