Replace hardcoded environment values in Makefile ports target with configurable variables

[Copilot]

The ports target had hardcoded environment-specific values (calypr-demo.ddns.net, 100.22.124.96) that would not work for other deployments.

Changes

• New variables added to Makefile configuration section:

  • TLS_SECRET_NAME (default: argo-tls) - TLS secret name for certificates
  • EXTERNAL_IP (optional) - external IP for ingress, skipped if unset

• Updated ports target to use:

  • ${ARGO_HOSTNAME} for Let's Encrypt certificate paths
  • ${TLS_SECRET_NAME} for all TLS secret references
  • ${EXTERNAL_IP} with conditional assignment

Usage

export ARGO_HOSTNAME=my-domain.com
export EXTERNAL_IP=192.168.1.100      # optional
export TLS_SECRET_NAME=my-tls-secret  # optional, defaults to argo-tls
make ports
