Subject: [PATCH] Build: imagen autocontenida, .dockerignore y limpieza de
 requirements

- Dockerfile copia el proyecto Django, no la raiz del repo, para que
  manage.py y wsgi.py queden donde gunicorn los espera
- collectstatic en tiempo de construccion y CMD en la imagen
- .dockerignore: evita que .env, .git y artefactos locales entren en la imagen
- requirements.txt sin BOM
