Add Samba registry setup script for initial configuration

Script initializes Samba to use registry-based configuration:
- Creates minimal smb.conf with 'include = registry'
- Imports ZMB-optimized global settings into registry
- Configures shadow copy, ZFS integration, macOS support
- Restarts Samba services

Run on new systems with: sudo bash deploy/setup-samba-registry.sh
