Feat: Verbinden-Tab Rework — zwei Leitungen (Modell + Gedaechtnis) sichtbar getrennt

- Hero-Diagramm: lokaler Agent -> Leitung 1 (Gateway/Modell) + Leitung 2 (MCP/Gedaechtnis)
- Live-Status pro Leitung: neuer Endpoint GET /api/connect/health (llama-swap + mem0-Sidecar)
- Zwei nummerierte Setup-Spalten statt flacher Tab-Leiste; Memory-MCP aus tools{} geloest
- Claude-Code-Snippet: echte env-Anleitung (ANTHROPIC_BASE_URL/AUTH_TOKEN/MODEL + Shim-Hinweis),
  da Gateway kein /v1/messages bietet (live verifiziert: :9001 405, :8080 404)
- MCP-Scriptpfad jetzt klar nur Leitung 2 zugeordnet
