UIU-2026 format currency values as currencies, not numbers

[vashjs]

Ref: UIU-2026

So this module uses both classes and functional components; several localization methods were created for currency values.
useLocalizeCurrency hook - for functional
localizeCurrencyAmount function - for class ones (but it is also part of the hook)

After this PR is merged, all currency numbers will be with a prefix that corresponds to the currency (information about this exists in the stripes context).
Also in many places a small refactoring was made, and instead of parseFloat(value).toFixed(2) the util function formatCurrencyAmount was replaced.

Please see screenshot with differences:

After:

NOTE: there aren't functional changes, so problems with coverage cames from previous implementation.

@vashjs The code coverage has to be at least 80%.
It is too quick to merge a PR the very next day inspite of it involving too many files to review. I do not know why this PR was approved without the minimal code coverage being acheived.
I would request you to work on the unit tests in increasing the code coverage. If that is not possible, please explain the reason for the same.

@vashjs please create a ticket to cover new code with unit tests

If you look at my changes, there are a lot of them BUT they are not functional changes, I just added currency localization in all places. Regarding approvals, I had enough of them to merge the changes.

Since many files have changed, sonar showed all the places in the affected files where the team that owns the "ui-users" module did not cover the functionality with tests.

Before my changes, the ui-users module had 70% coverage, after my changes it was 70.2%, I did not cause any damage to the module regarding coverage.
