SortFilterSeriesPanel: add new input for limit

Created by: unclejustin

The limit field is currently a number input. We want the ability to disable the arrows when the limit would be "out of bounds".

If the limit is currently at max, disable the up arrow. If the limit is currently at 1, disable the down arrow.

This requires a custom component, as disable the arrows separate from the entire input in a number input field is not possible.
