Verlauf-Grafik aus Sim-Schema (mehrere Linien) + Ampelbalken in allen Spalten

- renderRunsLineChart nutzt wieder SIM_METRICS statt highlights -> deckt auch
  Module ohne Highlight-Def ab (weltkueche/fluss zeigten sonst nur Sterne);
  Snapshot bei einem Durchgang via renderSimMetrics-Kacheln
- Modul-Tabelle: Ampelbalken auch fuer Durchgaenge, Spielzeit, Zuletzt
  (mehr/aktueller = gruen) -> alle Spalten konsistent grafisch
