Update Technitium compose files to match official example

- Switch from host to bridge networking with port mappings
- Add environment variables for DNS domain, admin password, HTTPS config
- Add hostname (dns01/dns02) and update container names
- Add sysctls for network port range
- Change restart policy to unless-stopped
- Add commented port options for DoT, DoH, DoQ, DHCP
- Maintain Synology-specific settings (mem_limit, cpu_shares, security_opt)
