Fix mount sounds with real MPQ paths and family detection

Mount Sound System:
- Use actual creature sounds from MPQ (Horse, Ram, Wolf, Tiger, Dragons)
- Separate sound pools: jump (attack), landing (wound), rear-up (aggro)
- Mount family detection: HORSE, RAM, WOLF, TIGER, RAPTOR, DRAGON
- Family logged on mount for future per-family sound selection

Sound Mappings:
- Flying mounts: Dragon wing flaps + DragonHawk screeches
- Ground mounts: Horse attack (jump), wound (land), aggro (rear-up)
- Ready for family-specific sound selection (TODO)

Mount Lean:
- Procedural lean into turns for ground mounts
- Physics-based: turn rate × 0.15, max ±14°, 6x/sec blend
- Returns to upright when not turning or when flying
- Rider follows mount roll automatically via bone attachment
