feat: enhance configuration and network management logging

Browse Source 
Add comprehensive logging to configuration management and network operations
across all supported platforms to improve visibility into system setup and
network configuration processes.

Key improvements:
- Configuration initialization and validation logging
- CLI flag processing visibility (listen, log, cache flags)
- IP allocation/deallocation tracking across platforms
- DNS configuration operations logging (Linux, macOS, FreeBSD)
- Upstream bootstrap and fallback operation tracking
- Listener configuration initialization logging

This provides complete visibility into configuration management and network
setup operations, helping identify configuration issues and network setup
problems across different platforms.
