Add workflow dispatch support for custom pipeline variables

- Add workflow_dispatch inputs for image_tag, detector_config, and detector_version
- Make container image tag configurable via IMAGE_TAG variable in GitLab CI
- Pass workflow inputs as variables to GitLab pipeline trigger
- Set sensible defaults for all configurable variables

This allows manual workflow triggers with custom container images
and detector configurations while maintaining backward compatibility.
