rendering/game: track per-entity swim state for correct water animations

Browse source 
- Add creatureSwimmingState_ map to track which units are swimming
- unitAnimHintCallback with animId=42 (Swim): marks entity as swimming
- unitAnimHintCallback with animId=0 (MSG_MOVE_STOP_SWIM): clears swim state
- Per-frame sync: uses Swim(42)/SwimIdle(41) when swimming, Run(5)/Stand(0) otherwise
  — creatures/players now show SwimIdle when standing still in water
- Clear creatureSwimmingState_ on creature/player despawn and world reset
