feat: implement SMSG_PLAY_SPELL_VISUAL with SpellVisual DBC chain lookup

Browse source 
Parse SMSG_PLAY_SPELL_VISUAL (casterGuid + visualId) and spawn a
transient M2 spell effect at the caster's world position.

DBC chain: SpellVisual.dbc → SpellVisualKit.dbc → SpellVisualEffectName.dbc
Lookup priority: CastKit.SpecialEffect0, fallback to MissileModel.
Models are lazy-loaded and cached by path; instances auto-expire after 3.5s.
DBC layouts added to all four expansion layout files (Classic/TBC/WotLK/Turtle).
