Fix VPS IP address (66.63.182.168 → 51.222.12.162) + Add Minecraft port forwarding

CRITICAL CORRECTION:
- Old deprecated VPS: 66.63.182.168 (DO NOT USE)
- Current VPS: 51.222.12.162 (vps-3fce361e.vps.ovh.ca, OVH Canada)
- WireGuard IP: 10.0.9.1 (confirmed via SSH)

Added Minecraft ATM10 port forwarding:
- External: 51.222.12.162:25568
- Internal: 10.0.10.46:25568 (via WireGuard tunnel)
- iptables DNAT + MASQUERADE rules configured
- Rules saved to /etc/iptables/rules.v4 (persists across reboots)
- SRV record: _minecraft._tcp.atmons.deadeyeg4ming.vip → 51.222.12.162:25568

Updated files:
- All 6 documentation files with correct VPS IP
