Read armor resists from the cache template EnumMap

Resists.getArmorResists and NPCManager.applyEquipmentResists now read
cacheTemplate.getCombatAttackResist() with DamageType keys instead of the
legacy String-keyed map, and default a missing key to 0 instead of an
unboxing NPE.

Offline parity (scripts/p15a.py, all 7586 static_item_templates rows vs
the template CObjectIndex.lookup picks): 0 differences in the full
combat_attack_resist map. Every ITEM/DEED/RUNE template carries all 16
keys, so no value changes. No comparator added or removed.
