feat: add UnitClassification Lua API for nameplate and boss mod addons

Browse source 
Returns WoW-standard classification strings: "normal", "elite", "rareelite",
"worldboss", or "rare" based on creature rank from CreatureCache. Used by
nameplate addons (Plater, TidyPlates) and boss mods (DBM) to detect elite/
boss/rare mobs for special handling.
