feat(13-04): NetServer-Adapter fuer tender24/lhs-vpbw/vergabe.landbw (INGEST-02)

- Package-Legitimacy-Checkpoint bestaetigt: cheerio (sauberer Gate-Pass,
  27M Downloads/Woche) statt node-html-parser installiert
- EIN config-getriebener NetServerAdapter bedient alle 3 AI-AG-Portale
  via PublicationSearchControllerServlet-Trefferliste, parst <table> mit
  cheerio zu RawTenderRecord[], sourcePortal je Zeile korrekt
- sourceNoticeId = data-oid (stabil, per Zeile eindeutig); sourceUrl =
  Such-URL als dokumentierter Best-Effort-Fallback (kein Deep-Link ohne
  JS-Ausfuehrung ermittelbar, Open Question 2)
- Fehlertoleranz: try/catch pro Zeile + pro Portal, []-Fallback bei
  Totalausfall, AbortController 15s-Timeout, hardcodierte Portal-URLs
  (SSRF-Guard T-13-04-01)
- Live-gecapturte Fixture (tender24.de, 2026-07-23) mit Umlaut-/&amp;-
  Buyer, gefuellter und leerer Deadline; 14 Spec-Tests gruen
