Subject: [PATCH] Expose minecraft server over TCP via MetalLB

Minecraft Java Edition uses raw TCP on port 25565, not HTTP. The previous
ClusterIP Service + HTTP Ingress (Traefik 80/443) could not carry TCP 25565
traffic, so minecraft.rogi.casa:25565 was unreachable.

- Change Service to LoadBalancer with fixed IP 10.88.20.103 (dmz-pool),
  matching the pihole-dns pattern, so port 25565 is exposed directly.
- Remove the dead HTTP ingress (it routed HTTP to a TCP game port).
