General improvements to "Damaging Hits" section and armour breakdown.

[QuickStick123]

Fixes #4240.

Description of the problem being solved:

The calculations for armour mitigations are very vague/confusing and have minimal breakdowns.
Spell suppression isn't included if it is guaranteed against spells.
Certain breakdown sections don't hide when irrelevant.
Generalised and separate resistances and base damage reduction. This makes it much easier to handle large changes to this in the future and allowed explicit references to damage types to be removed.

I found a couple of minor improvements, but this definitely looks a lot clearer. One thing that is outside of scope for this PR, but we'll eventually want to fix is that armour reductions should only be applying to attacks, not spells.
