Implement comprehensive audio control panel with tabbed settings interface

Adds complete audio volume controls for all 11 audio systems with master volume. Reorganizes settings window into Video, Audio, and Gameplay tabs for better UX.

Audio Features:
- Master volume control affecting all audio systems
- Individual volume sliders for: Music, Ambient, UI, Combat, Spell, Movement, Footsteps, NPC Voices, Mounts, Activity sounds
- Real-time volume adjustment with master volume multiplier
- Restore defaults button per tab

Technical Changes:
- Added getVolumeScale() getters to all audio managers
- Integrated all 10 audio managers into renderer (UI, Combat, Spell, Movement added)
- Expanded game_screen.hpp with 11 pending volume variables
- Reorganized settings window using ImGui tab bars (Video/Audio/Gameplay)
- Audio settings uses scrollable child window for 11 volume controls
- Settings window expanded to 520x720px to accommodate comprehensive controls
