feat(src/djinit/templates): introduceVite‑powered React frontend scaffold and django‑vite integration

Add a minimal React frontend template (index.html, App.jsx, index.css, main.jsx) and configure static asset handling.
Update Docker Compose to populate DATABASE_URL according to the selected database type.
Include django‑vite in the template requirements and settings.

- New Features
  - Scaffold `frontend` directory with React components and Vite entry point.
  - Configure static URLs, root, and alias via `STATIC_URL`, `STATIC_ROOT`, and `DJANGO_VITE_ASSET_SRC`.
- Enhancements
  - Dynamically set `DATABASE_URL` in `docker-compose.yml` for PostgreSQL or MySQL.
  - Add `django-vite` to `THIRD_PARTY_APPS` and `requirements-tpl`.
- Bug Fixes
  - None.
