[FEATURE] Misleading conflicts

[jtsage]

So, if a mod as flagged as conflicting, we should visually not (and possibly allow to hide) those mods that are either inactive or missing, so as not to mislead that there is an active problem.

I think this would sort the last of the suggestions from Taco29.

Timeline: next few days.

Dev notes: add a flag isActiveProblem to the conflict loop, flag true if isActive == true and isMissing == false - for those that !isActiveProblem display as text-muted, and add a class name and toggle to remove them from the listing.
