When lead time falls into today but due to availability today is not scheduled - day is still clickable

[Valentina R]

If availability is from 09:00 to 17:00, lead time is 6 hours and current time is 15:00, today is still clickable. Since there are no slots it just confuses the customers thinking there should be one.

It would be great if days that have no slots could not be clickable instead of showing ‘no slots’ when selected.
