CurrencyInput

Money field with a currency symbol prefix and locale-aware thousands/decimal separators probed from Intl.NumberFormat, so th-TH, en-US and de-DE each format correctly. onAccept hands back both the numeric value and the display string, and scale/min/max control the fractional digits and clamp the amount as it is typed. Right-aligned monospace tabular figures; ships THB, USD, EUR, GBP and JPY presets.
