Tighten WMO collision detection when inside buildings

When inside a WMO, use:
- Smaller sweep step size (0.20 vs 0.35) for more frequent collision checks
- Tighter player radius (0.45 vs 0.50) for less claustrophobic corridors
- Stronger push response (0.12 vs 0.08 max) for more responsive walls

Prevents clipping through walls in tight indoor spaces while keeping
outdoor movement smooth.
