Expenditures: Number formatting on all numbers

[arrenv]

Description

There should be number formatting on all numbers within the Expenditures feature. This should use the existing Numeral component to maintain consistency with the rest of the DApp.

The latest version of this should be on master as merged in this PR recently https://github.com/JoinColony/colonyDapp/pull/4052

Here is an example of the unformatted numbers:

TO Do

• [ ] Check all the numbers that need formatting. (Modals, different payment types, different stages, etc.)
• [ ] Add the formatting.
• [ ] Ensure the UI does not break with the formatting added.
