fix: respect number format in currency input (#18469)

Fixed #18355 

Currency fields ignored the workspace number format when editing:
display showed e.g. 5 982,77 € (French style) but the input forced US
style (5,982.77) and rejected comma as decimal.
Fix: CurrencyInput now uses useNumberFormat() and passes the correct
thousandsSeparator and radix to the IMask input so edit mode matches the
chosen format (comma/space, dot/comma, etc.).
Files: CurrencyInput.tsx (use format for mask), new
CurrencyInput.test.tsx .
