Reduce city stutter: lower spawn rate, resync interval, M2 render distance

Browse source 
- MAX_SPAWNS_PER_FRAME 8→3 (each spawn does sync M2 load, 5-50ms each)
- Creature resync scan interval 1s→3s (O(N) entity iteration)
- M2 render distance: add 1000+ instance tier at 500 units, reduce 2000+
  tier from 350→300 units to cap draw call count in dense cities
