feat(class): add CoA custom-class stat-summary defaults via CoAClassPrimaryStats

Copy CoAClassSpecData.lua into the addon folder and load it before
RatingBuster.lua in the .toc.  After the vanilla if/elseif ladder in
applyClassProfileDefaults(), a new CoA branch checks
CoAClassPrimaryStats[cls]: if the player's token is a CoA custom class,
enable the stat-summary keys that match the class's union of primary
stats (Agility→physical melee block, Strength→physical melee block,
Intellect→spell block, Spirit→healing/mp5 block, Stamina→health/sta).
Vanilla classes and unrelated settings are not touched.
