Disabled pagination buttons don't look disabled

[cellio]

A row of pagination buttons includes "previous", numbered pages, and "next". If one of those isn't actually available, for example "previous" when you're on page 1, you can't click on it -- but it looks like you can, because it's the same color or close enough as makes no difference. Disabled buttons should be visually disabled -- more gray, for example -- and as a stretch goal, if you mouse over them the cursor could change to the "no" symbol.

(Not sure if this is qpixel or co-design.)
