Canonical: Redirect when front page's paginated states not found. 

Perform a canonical redirect for an invalid pagination request of a static front page.

When a site has a static front page assigned and that page has a `<!--nextpage-->` within its content, previously accessing non-existing pages (e.g. `example.com/page/3/`) did not redirect or return a 404 or 301. This changeset resolves that issue by performing a canonical redirect.

Unit tests are also included for this specific use case and to ensure the fix does not affect a blog listing home page.

Follow-up to [47738], [47727], [34492].
