Add configurable UDP scanning and numeric IP sorting

- Add UDP_SCAN_ENABLED and UDP_PORTS environment variables to control UDP scanning
- UDP scanning disabled by default for faster scans
- Support port ranges (100-200), lists (53,67,68), or mixed formats
- Sort IPs numerically by octets in site management modal
