perf: constexpr reciprocals, cache redundant lookups, consolidate texture maps

Browse source 
- Hoist DBC field index lookups before loops in game_handler (7 DBC iteration loops)
- Cache getSkybox()/getPosition() calls instead of redundant per-frame queries
- Merge textureHasAlphaByPtr_ + textureColorKeyBlackByPtr_ into single map
- Add constexpr for DEG_TO_RAD, reciprocal constants, physics delta
- Add reserve() for WMO/M2 collision grid queries and portal BFS
- Frustum plane normalize: inversesqrt instead of length+divide
- M2 particle emission: inversesqrt for direction normalization
- Parse creature display IDs from query response
- UI: show spell names/IDs as fallback instead of "Unknown"
