build: don't use local dependencies, and remove backend package: hatch doesn't support yet editable dependencies (https://github.com/pypa/hatch/issues/588), and to work on dev, backend and templates must be installed manually in dev mode. To avoid issues during sync when entering a shell, those dependencies are disabled and must be installed manually.
