Improve EHP accuracy (#552)

* Improve EHP accuracy

* Missed overkill from life loss prevention.

* Implement damage order reversal when losing pools

* Undo adding chaos ES double damage to PoolsLost and rename PoolsLost to reflect it's usage for recoup

* Hunting more corner cases

MoM with ES when there is ES bypass was not capping effective ES.
MoM with life loss prevention was not accounting for the multiplied life effectiveness when reducing pools.
Max hit smoothing (for conversion + armour) now uses pool reduction to effectively home in on a precise max hit.

* Port defence tests from pob1

* Defence test changes for poe2
