Filter consent records by version number

Replace the opaque cookieBannerVersionId filter with an
integer version filter. The SQL filter now resolves the
version number via a subquery against cookie_banner_versions.

Also fix the CookieBannerVersion resolver on consent records
to load the full version from the database instead of
returning a stub with only the ID set (which caused the
version to always display as 0).
