feat(src/djinit/creators): add Dockerfile and .dockerignore generation for new projects

Introduce automatic creation of Dockerfile and .dockerignore during project scaffolding, enabling container‑ready setups out of the box.

* New Features
  - `create_dockerfile` method renders Dockerfile with configurable context (module name, database type, Tailwind usage).
  - `create_dockerignore` method generates a .dockerignore file to exclude unnecessary files from containers.
* Enhancements
  - Added both methods to the setup pipeline in `SetupCreator` so they are executed automatically.
  - Context values are derived from project metadata, allowing customization per project.
* Bug Fixes  - None
