Ideas

In services/formService.ts you are using an outdated package for formatting numbers. Instead you can use https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/NumberFormat

I suggest the following
```

export function formatDecimalValue(culture: string, value: string) { return Intl.NumberFormat(culture).format(parseFloat(value)) ?? NaN;}
