UI Phase 1: Statistik 50/50, Footer rechts, Linksammler bis Footer, Bandbreiten-Graph oben rechts, Stat-Karten + Hilfe-Untermenues

Sichtbarkeits-/Layout-Politur (User-Wunsch, Quick-Wins-Paket vor den groesseren
Reworks von Einstellungen-Tab und Account-Verwaltung):

- Statistik: Bandbreitenverlauf und Hoster-Statistik jetzt 50/50 statt 40/60
  (grid-template-columns 1fr 1fr).
- Footer: die Zaehler (Pakete/Links/Session/Gesamt/Hoster/Speed/ETA) wandern
  nach unten-RECHTS, die Aktions-Buttons (Ein-/Ausklappen, Leeren, Clipboard)
  nach links.
- Linksammler: das Textfeld fuellt jetzt die volle Hoehe bis zum Footer
  (collector-view: grid-row 1fr, textarea flex:1) statt bei 220px zu enden.
- Downloads-Tab: neuer Bandbreiten-Graph oben rechts (DownloadSpeedSparkline)
  neben der Suche. Eigener 250ms-Timer mit geglaettetem Verlauf: bei kurzem
  Einbruch auf 0 faellt die Kurve nicht hart ab, sondern gleitet weich runter
  (asymmetrisches Easing: schnell hoch 0.45, langsam runter 0.12) und
  korrigiert sich wieder; die angezeigte Zahl bleibt der echte aktuelle Wert.
  Erste Version - Optik wird nach JDownloader-Screenshot nachgezogen.
- Stat-Karten professioneller: Wert in Zahl + Einheit getrennt (Einheit
  dezent), ruhige Leerzustaende (idle '0'/'—' gedaempft statt nacktem grossen
  '0'), kompaktere Karten, dezentere Eyebrow-Labels.
- Hoster-Balken: flacher Akzent statt Neon-Verlauf (kein Gradient).
- Hilfe-Menue umstrukturiert mit Hover-Untermenues: 'Logs oeffnen' (Haupt-,
  Audit-, Rename-, Session-, Trace-Log), 'Remote-Support' (Support-Bundle +
  Support-Trace), 'Diagnose' (Debug-Setup + Debug-Token); 'Letzte Fehler
  anzeigen' und 'Suche Aktualisierungen' bleiben direkt.

Reine Renderer-Aenderung (App.tsx + styles.css). 808 Tests gruen, tsc=6
Baseline, Build ok.
