Replace 2D ImGui text markers with proper 3D billboard sprites using BLP textures. Features: - Billboard rendering using Interface\GossipFrame\ BLP textures (yellow !, yellow ?, grey ?) - WoW-style visual effects: bob animation, distance-based scaling, glow pass, distance fade - Proper NPC height positioning with bounding box detection - Camera-facing quads with depth testing but no depth write - Shader-based alpha modulation for glow and fade effects Technical changes: - Created QuestMarkerRenderer class with billboard sprite system - Integrated into Renderer initialization for both online and offline terrain loading - Rewrote updateQuestMarkers() to use billboard system instead of M2 models - Disabled old 2D ImGui renderQuestMarkers() in game_screen.cpp - Added debug logging for initialization and marker tracking Quest markers now render with proper WoW visual fidelity.
