DiviPage::builderUrl() is shared by DiviPage::editUrl() and the content
composer, which now returns edit_url; content-create without divi keeps
the wp-admin link. divi-write-smoke checks the builder URL and, new in
section 9, the M1/M2 gates live (raw Divi markup refused; Divi read-only
stops content-create divi and execute-ability lit/divi-insert).
