feat: separate Public IP for DNS records from Server IP, improve settings help texts

Browse Source 
- Add public_ip field to Settings for DNS A records (proxy/load balancer IP)
- DNS records now use public_ip, falling back to server_ip if empty
- Server IP renamed to "Server IP (Docker Host)" for clarity
- Public IP labeled "Public IP (DNS Target)"
- Updated help texts for domain, server IP, public IP, and Docker network
- DB migration + schema for public_ip column
