Merge feat/dsms-stufe3-version-chains: version chain history + diff + audit-timeline modal

VW & andere unbekannte CMPs liefern 603-Wort-Bug: kein Named-Matcher
greift, generische Heuristik filtert oder size_kb < 5 → cmp_cookie_text
bleibt leer → Backend faellt auf 603-Wort DOM-Navigation zurueck.

Neuer INFO-Log fuer jede JSON-Response >=3KB die als CMP-Kandidat
ueberlebt, aber Heuristik ODER Size-Schwelle nicht passt. Top-Keys +
URL + Size — beim naechsten VW-Run sofort sichtbar, welcher Endpoint
ein Named-Pattern braucht.
