fix(blog): thread route id through buildAuthorMetadata for canonical URL

Author pages for unknown/unmatched ids fell back to author?.id, which is
undefined when no post matches — collapsing canonical/OG URLs to
{basePath}/authors/ instead of {basePath}/authors/{id}. Pass the route id
explicitly so canonical always resolves correctly.
