fix: money in words

[barredterra]

[!NOTE] Please wait for #27178 to reduce the diff. Until then, please look at the last commit (06fd6f6) only.

Money in words does not work correctly for fractions that are not a factor of ten (10, 100, 100). For example, some currencies have five fraction units constituting one main unit, i.e. $ 1 == 5 cents and $ 0.2 == 1 cent.

This PR solves this by:

• Using the fraction_units from the Currency definition instead of guessing them from the number format's decimal places.
• Calculating fraction * fraction_units instead of just treating the fraction as an integer.
• Adding a test case for this scenario.

Todo:

• [ ] check if we can remove Number Format from Currency (rely on the fraction units only) (related bug: #26584)?
