Issue 3979 fix numberinput form validation

[cyantree]

Fixes #3979 and #3982.

Based on #3756 I reworked the data flow handling to be more in line with other components again.

This means onChange() will be triggered on input again but still outputs validated and clamped data.

I've also added a test for the expectation that onChange() and onBlur() won't get called in the same run which might lead to the onBlur() handler working with old data in case it's using data stored via useState() hook.

Maybe that's something that should be added to all input components.

I also removed the higherPrecision handling introduced in #3756. For controlled components it allowed display values with higher precision than allowed. Like:

<NumberInput precision={0} value={1.23} />

would output 1.23. However when changing the value manually afterwards it would fall back to the configured precision.
Because this might be confusing I dropped this behaviour again. Sorry for that.
However if you find this useful I can revert this change.
