Single Source of Truth: Frontend/Backend-Ungereimtheiten ausgeraeumt (Review 15.07.)

Backend (Wahrheit reparieren):
- gateway_reachable() prueft jetzt den ECHTEN mc2-gateway (:9010 via V1_UPSTREAM)
  statt nur die Engine - toter Denkpfad war in Health/Cockpit unsichtbar
- /api/system/services vollstaendig: + LLM-Gateway, + Steuerpult, + Waechter
  (mc2-steward via is-active); scope-Feld (user/system); mc2-gateway/mc2-steward
  in die Restart-Allowlist
- Connect-Health Leitung 1 prueft den Client-Pfad (V1_UPSTREAM statt llama-swap)
- agent_status liefert pc_executor_url (UI zeigte hartcodierte IP/Ports)
- SSE-Endlosschleife gefixt: /api/auftragsbuch schrieb announce-branches bei JEDEM
  Aufruf neu -> mtime-Bump -> invalidate -> Refetch im 3-s-Takt je Client;
  jetzt nur noch bei echter Aenderung

Frontend (ein Datenweg):
- SystemDrawer komplett auf React-Query-Hooks (vorher eigenes 3-s-setInterval auf
  dieselben Endpunkte inkl. teurem Updates-Check); Dienste-Liste = Backend-Antwort
  (SERVICES-UI-Kopie geloescht); useDialog statt Eigenbau; fmtBytes statt Duplikat
- useLucyHealth: Dienst-Matching per systemd-unit statt Namensfragment; Gateway-
  Reparatur zielt auf mc2-gateway; neuer Waechter-Check; Backend-tot => ehrliches
  rotes Verdikt statt eingefrorener letzter Stand (auch Sidebar)
- Toter Code raus: views/models/Cockpit.tsx (908 Z.) + RoleAssignModal + Placeholder;
  LaneEditor (Routing-Policy) + WarmSetManager damit ZURUECK im UI als Tab
  "Routing & Warm-Set" im Modell-Manager
- Cockpit: blockierte Ideen-Karten erscheinen in "Braucht dich" + Kachel-Hint;
  Verbinden-Kachel zeigt 3 Leitungen live statt hartem "Zed"
- Maschinenraum: ehrliches "frei" (reale Belegung) + eigenes KV-Cache-Segment
- AgentView: Ports/PC-Adresse aus der API; Guide lehrt Lanes chat/coding
- queries.ts: useModels nutzt SSE-relax; Chronik-Limit im Query-Key;
  useJobs/useZeitmaschine mit enabled-Schalter

Verifiziert: tsc+vite gruen, Backend-Smoke beide Gateway-Modi, UI live gegen die
Box (Cockpit/Werkbank/Routing-Tab/Drawer rendern mit Echtdaten).
