feat: add quick and advanced modes for LXC container creation
Users now have two options when creating the LXC container: 1. Quick mode - Uses optimized defaults for production (2GB RAM, 16GB disk, etc) 2. Advanced mode - Full control over all settings like the community script Advanced mode allows customization of: - Memory, CPU cores, CPU limits, swap - Static IP vs DHCP - DNS servers - Firewall settings - Privileged vs unprivileged - Auto-start on boot - Startup order This gives users the best of both worlds - quick setup with good defaults or full control when needed.
