feat: add UnitArmor and UnitResistance for character sheet addons

Browse source 
UnitArmor(unit) returns base, effective, armor, posBuff, negBuff
matching WoW's 5-return signature. Uses server-authoritative armor
from UNIT_FIELD_RESISTANCES[0].

UnitResistance(unit, school) returns base, effective, posBuff, negBuff
for physical (school 0 = armor) and magical resistances (1-6:
Holy/Fire/Nature/Frost/Shadow/Arcane).

Needed by character sheet addons (PaperDollFrame, DejaCharacterStats)
to display armor and resistance values.
