feat(GradeRangeSlider): add typeable min/max inputs
- Add inputs alongside the slider so values can be typed directly, not just dragged - Clamp typed/dragged values to [min, max] - Animate the slider with a sine ease when a value is typed, keeping the drag unanimated - Meet min/max values instead of letting fields swap mid-keystroke - Combine min/max handlers into one `onInput` function
