[Feature] Default preloaded enemy stats per content type

[fribbels]

Motivation

Currently the user has to specify an enemy level and RES %.

Objective

Allow the user to preselect a type of boss, like "MoC 12 Kafka" or something and fill out the boss's corresponding stats by default without having to look it up

Note: Low priority since there's only a couple types of content right now and endgame is just level 95
