Move Dockerfile.frontend, .backend, .exporter, .mcp and .storybook
under docker/images/ from ubuntu:26.04 / nginx-unprivileged / a
manual Node tarball install to Docker Hardened Images (Debian 13,
or Alpine for storybook). storybook and mcp get a true non-dev
runtime; frontend, backend and exporter keep the -dev tag as their
final image, since each needs a shell and/or package manager at
container runtime (nginx templating, fontforge/python3, and a
headless-browser stack, respectively).
* ⬆️ Updgrade base image for penpot docker images to ubuntu 26.04
