Remove configurable APP_VERSION and define it in code

The APP_VERSION variable is no longer configurable via the `.env` file or environment settings. Instead, the version is now hardcoded in `backend/app/core/config.py` as `NEXAPG_VERSION` and accessed through a property. This change simplifies version control and ensures consistency across deployments.
