Add dedicated module dependency and network services

- Added depmod.yaml service for rebuilding kernel module dependencies
- Added network.yaml service for DHCP network configuration with proper dependencies
- Cleaned up udev.sh to remove depmod call (now handled by dedicated service)
- Updated udev-trigger.yaml to depend on depmod for proper module loading order
- Ensures overlay.ko and other kernel modules have correct dependencies before hardware detection
