Fix calculation when using Unexciting Runegraft (#9251)

I implemented the Unexciting mod incorrectly in the past making it negate any lucky or unlucky mod instead of applying the correct formula
Unexciting rolls three times and keeps the median result -> 3p^2 - 2p^3

This affects Block Chance, Suppress chance and crit chance

Also changed the sidebar for Block and Suppress chance to use 3 and 2 significant figures as when using azadi's crest for double lucky the block chance values can easily get to 99 and require more precision
Made sure so add a new handler that trims off 0 after the decimal so regular block builds don't show 75.000% block
