🐞 Neighborhood: Link explicitly to the Neighborhood URL.

- #892
- #74

I noticed that the `Convene` link in the footer was always to the
current `root_url`, which will be the `Space` when visiting the `Space`
via a `Domain`.

This shifts it to use the `APP_ROOT_URL`, and allows `Operator`s to
configure the Neighborhood name and Tagline.
