get_anayasa_document_unified 404'd when a /ND/ (Norm Denetimi) path was
supplied on the bireysel host (kararlarbilgibankasi) instead of the norm
host. Detection was netloc-first and passed the wrong-domain URL through
unchanged.
Add normalize_anayasa_document_url(): classify by path (/ND/ vs /BB/) and
re-key the host to the canonical domain, preserving query/fragment. Route
get_document_unified() off the normalized result. Verified end-to-end: the
previously-404 URL now returns the decision markdown.
