Link cookie policy doc and revamp tracker rows

Expose the generated cookie policy Document on the CookieBanner
GraphQL type through a nullable policyDocument field and resolver,
and surface a link to it from the banner configuration header next
to the origin and ID. The link is hidden until a banner version is
published and the document exists.

Rework the tracker table rows: drop the Source column in favour of
a tracker Type badge, and move each tracker's description inline
beneath its name (and into the add/edit row inputs) instead of a
separate Description column.
