Forward QUIC UDP port and set --enr-quic-port for both mainnet and hoodi variants

	ports:

	- "9100:9100/udp"

Anchor uses two UDP ports for P2P (discovery + QUIC). The current docker compose only forwards discovery; QUIC is unreachable.

Without this, peers attempting QUIC connections fail and fall back to TCP. Reduced peer count / connectivity, especially during churn — relevant for SSV operators where QBFT round timers are tight.

Anchor's QUIC port should be P2P_PORT + 1 per https://github.com/sigp/anchor/blob/8f4839625e9791d31c9159930cc00af2bd7ce2d5/anchor/client/src/cli.rs#L175-L218.

Mainnet (package_variants/mainnet/docker-compose.yml)

services:
  operator:
    build:
      args:
        NETWORK: mainnet
        P2P_PORT: 9100
        QUIC_PORT: 9101    # new
    ports:
      - "9100:9100/tcp"
      - "9100:9100/udp"
      - "9101:9101/udp"    # new

Hoodi (package_variants/hoodi/docker-compose.yml)

Same shape: add QUIC_PORT: 9103 to build args and "9103:9103/udp" to ports.

Dockerfile (operator/Dockerfile)

Declare the new build arg and re-export it as a runtime env var:

ARG NETWORK
ARG P2P_PORT
ARG QUIC_PORT          # new
ARG STAKER_SCRIPTS_VERSION

ENV P2P_PORT=${P2P_PORT} \
    QUIC_PORT=${QUIC_PORT} \    # new
    HTTP_PORT=5062 \
    STAKER_SCRIPTS_URL=https://github.com/dappnode/staker-package-scripts/releases/download/${STAKER_SCRIPTS_VERSION}

Entrypoint (operator/entrypoint.sh:54-69)

Append --quic-port=${QUIC_PORT} to FLAGS next to --port=${P2P_PORT}.

Also: ENR advertisement

Forwarding the QUIC UDP port without setting --enr-quic-port is half a fix: the port is reachable, but the ENR doesn't advertise it, so peers don't know to dial it. From Anchor's advanced_networking docs:

"Anchor does not yet support ENR auto-update — we therefore recommend manually setting publicly reachable ports via the --enr*-port CLI parameters to advertise your node as reachable on the network."

Recommendation: also set the matching ENR-port flags in entrypoint.sh:

--enr-udp-port=${P2P_PORT} \
--enr-tcp-port=${P2P_PORT} \
--enr-quic-port=${QUIC_PORT} \
