feat(src/djinit/creators): add API v1 URL integration for predefined structures and enhance context variables

- Add conditional logic to `_add_to_api_v1_urls` when `structure_type` is `"predefined"`
- Include `module_name` in contexts for `justfile` and `Procfile` templates
- Clarify `module_name` usage in `.env.sample` generation comment
