feat: Antrag-Detail News-Match-Box + Test-Coverage fuer aktuelle-themen

**News-Match-Box im Antrag-Detail:**
Reverse-Sicht zur /aktuelle-themen-Seite — pro Antrag-Detail-Page eine
Box "Aktuelle News passend zu diesem Antrag" mit den Top-5 Matches der
letzten 90 Tage. Pro News-Card direkter "PM-Vorschlag generieren"-Button
mit Idempotenz-Check (bestehender Draft wird ohne LLM-Call zurueckgegeben).

Loesst das User-Feedback "ich oeffne ja meist Antrags-Detail, nicht den
News-Tab — da fehlt mir die News-Sicht". Box laedt lazy via fetch und
bleibt komplett versteckt wenn keine Matches existieren (kein Noise).

**Test-Coverage fuer die heutigen Backend-Aenderungen:**

`tests/test_llm_bewerter.py`:
- 6 Tests fuer `_recover_unescaped_newlines` (clean, raw newline, tab+cr,
  outside-string, makes-invalid-valid, preserves-already-escaped)
- 2 Tests fuer `json_object_mode` pass-through (off → kein Param,
  on → response_format={"type":"json_object"})
- 1 Integration: Recovery greift im bewerte()-Loop ohne Retry

`tests/test_endpoints_smoke.py`:
- Vote-Orphans-Endpoint (GET) Smoke
- Vote-Orphans-Auto-Rate Auth-Wall
- Batch-Analyze Auth-Wall (incl. ALL-Modus)
- Aktuelle-Themen-Endpoints (top, zeitreihe, top-antraege, cluster,
  drafts-list, drafts-versions) — 8 Tests

`tests/test_batch_helpers.py`:
- 4 Unit-Tests fuer _enqueue_for_bl-Logik via Inline-Repro mit Mocks
  (already-rated skip, no-adapter, limit-cap, empty-text-skip)

Suite: 1084 passed, 50 skipped (Smoke-Tests skippen lokal weil
FastAPI nicht importbar, greifen aber gegen dev/CI).
