feat(src/djinit/creators): add Tailwind and HTMX toggles to generated settings

Add configurable `use_tailwind` and `use_htmx` flags to the Django starter project context, allowing users to optionally include Tailwind CSS and HTMX JavaScript libraries.

- New Features:
  - Introduce `use_tailwind` and `use_htmx` metadata flags in `base_settings_context`.
  - Propagate these flags to `requirements.txt`, generated `settings.py`, and CI configuration templates.
- Enhancements:
  - Ensure the flags are consistently available across all templated files.
- Bug Fixes: None.
