Add NumericUpDown for `long` and `double`

Is your feature request related to a problem? Please describe.
The current numeric controls only support Int32 and Decimal. This can be limiting when working with values that exceed the Int32 range or when floating-point semantics are more appropriate than Decimal.

Describe the solution you'd like
Add dedicated Int64 (long) and Double (double) UpDown controls, complementing the existing controls:

Already supported	Control	C# Type	Typical Use Cases
✅	NumericUpDown	int	Counts, quantities, indexes, IDs
❌	LongUpDown	long	Large IDs, file sizes, timestamps, large counters
✅	DecimalUpDown	decimal	Money, prices, tax rates, financial calculations
❌	DoubleUpDown	double	Scientific measurements, engineering values, coordinates, floating-point calculations
