fix: use localhost publicUrl and -max=100 for host-based Spark tests

Browse Source 
The previous fix enabled master-to-volume communication but broke client writes.

Problem:
- Volume server uses -ip=seaweedfs-volume (Docker hostname)
- Master can reach it ✓
- Spark tests run on HOST (not in Docker container)
- Host can't resolve 'seaweedfs-volume' → UnknownHostException ✗

Solution:
- Keep -ip=seaweedfs-volume for master gRPC communication
- Change -publicUrl to 'localhost:8080' for host-based clients
- Change -max=0 to -max=100 (matches other integration tests)

Why -max=100:
- Pre-allocates volume capacity at startup
- Volumes ready immediately for writes
- Consistent with other test configurations
- More reliable than on-demand (-max=0)

This configuration allows:
- Master → Volume: seaweedfs-volume:18080 (Docker network)
- Clients → Volume: localhost:8080 (host network via port mapping)
