Add comprehensive network diagnostic workflow

Adaugă 12 steps de diagnostic pentru a înțelege exact ce vede job container-ul:
- /etc/hosts și DNS config
- nslookup/dig/ping tests pentru hostname "gitea"
- Network interfaces și routing
- Test HTTP connections (hostname vs IP direct)
- Environment variables
- Comparație între gitea:3000 și 172.18.0.4:3000
