Add configurable container name support

- Add workflow_dispatch input for container_name (default: eic_xl)
- Add CONTAINER_NAME variable to GitLab CI (default: eic_xl)
- Update image path to use ${CONTAINER_NAME} variable
- Pass container_name from workflow to GitLab pipeline

This allows switching between different container images like
eic_xl and eic_ci via workflow dispatch.
