feat(dashboard): Dashboard-Redesign + Bugfixes + Pre-load

Bugs behoben:
- Topbar + Server-Panel: 'Kein Modell im VRAM' obwohl geladen → alle
  States (running/ready/loading/starting) werden jetzt erkannt
- Topbar zeigt bei geladenem Modell: Name + ctx-Größe + State mit Farbe

Dashboard-Redesign (OverviewPanel):
- KPI-Kacheln mit Farbe: .kpi.green/.red/.blue/.muted statt .tile
  (farbige Randlinien + farbige Werte wie im Referenz-Design)
- Icons pro Kachel (server, cpu, thermo, database)
- Stack-Liste: zeigt ctx/quant/GB, 'Laden'-Button wenn Modell bereit
  aber nicht geladen, ∞-Chip für immer-aktive Modelle
- 4. Schnellstart-Button: 'Tools verbinden'

Feature: Modell Vorwärmen (Pre-load):
- POST /api/preload?model=<name> — sendet Mini-Request an llama-swap
  damit es das Modell vorab lädt (max_tokens=1, kein Output)
- 'Laden'-Button je Modell in der Stack-Liste

Topbar CSS:
- Aktives Modell: teal-hinterlegter Pill wenn Modell geladen
- Kontext-Größe direkt neben Modellname angezeigt

Cookbook:
- Discover: genaue Zeitanzeige wann Quellen zuletzt befragt wurden
  ('vor X min / h / Tg.') statt nur 'aktuell'
