feat(about): add new pages for about section

Three new files have been added to the about section of the frontpage application:
- `addpage.tsx`: This file exports the `AddPage` component from the `EditablePages` feature and sets the access level to `private`.
- `notfound.tsx`: This file exports the `NotFoundError` component from the `common/components/errors` directory and sets the access level to `public`.
- `notfoundauth.tsx`: This file exports the `NotFoundErrorAuth` component from the `common/components/errors` directory and sets the access level to `public`.

These new pages have been added to enhance the functionality and user experience of the about section in the frontpage application.
