fix(footer): default nav + tagline when the tenant's CMS footer is empty

The unom tenant's footer doc has no sections yet (the multi-tenant migration
backfilled the old footer to the punktfunk tenant), so the footer rendered as
an empty, near-invisible bar. Render a sensible default (Übersicht/Rechtliches
links + site tagline) when there are no CMS sections; CMS content overrides it
once the unom footer is populated.
