numberdraginput: move under chonk components and cleanup API

[JonasBa]

The component should use InputGroup to add the trailing items and I've made some API changes that allow us to remove a few handlers and only rely on the native onChange

@evanpurkhiser any ideas why this might break our forms? I tested manually and the form still works as it used to (both creating new alerts and editing existing ones), but it seems the tests are busted.

I managed to figure it out. The step prop required the value to be n * step. I have removed it from the input for now
