feat(src/djinit/ui): add Vite/React selection support

- Add `UIFormatter.get_vite_choice()` to prompt inclusion of Vite/React via django‑vite
- Introduce `use_vite` flag in `StructureOptions`, store it in metadata, and propagate to scaffolding templates
- Update CLI prompts and final project summary to display Vite/React confirmation
- Extend usage of the flag throughout app generation to honor the selected frontend stack
