## **Description**
Previously there was a bug that affected the approve screen. When users
had a small spending cap (between 0.001 and 0.0001 or smaller), it was
coerced to 0.
This was caused by the method `new
Intl.NumberFormat(locale).format(spendingCap)` that applied the `1,000`
large number formatting, so the fix is to bypass it entirely for values
smaller than 1.
Additionally, these unformatted small numbers are presented in
scientific notation, so we leverage `toNonScientificString(spendingCap)`
to prevent that.
