fix: prevent crash when invalid characters typed in coordinate editor

Browse Source 
EditableNumberConverter.ConvertBack was throwing FormatException
when users typed '=' or other non-numeric characters, causing
WPF binding validation to crash the application on focus change.
Changed to return Binding.DoNothing to silently reject invalid input.
