fix: return caster unit ID from UnitBuff/UnitDebuff/UnitAura

Browse source 
The caster field (8th return value) was always nil. Now returns the
caster's unit ID ("player", "target", "focus", "pet") or hex GUID
string for other units. Enables addons to identify who applied a
buff/debuff for filtering and tracking purposes.
