Improve rendering distances, camera collision, and spawn point

- Increase WMO render distance from 1500 to 3000 units for better city loading
- Increase M2 render distance from 500 to 1000 units
- Increase terrain load radius from 4 to 6 tiles (~3200 units)
- Add raycast-based camera collision that zooms in when obstructed by walls/objects
- Move spawn point outside chapel to road near Stormwind gate
- Add ground height smoothing to prevent stumbling on uneven terrain
