Event-Thumbnails: Vorschaubilder mit Auto-Resize und Typ-Logos

- Migration: thumbnail-Spalte in events-Tabelle
- Event-Model: imageUrl() liefert Custom-Thumbnail oder Standard-Logo
  je Event-Typ (Logo_Training.png, Logo_Heimspiel.png, etc.)
- Thumbnail-Upload neben Typ-Auswahl bei Erstellen/Bearbeiten
  mit Live-Vorschau und Entfernen-Button
- Automatische Skalierung auf max. FullHD (1920x1080) via GD
  und Speicherung als JPEG (Qualität 85)
- Event-Listen (App + Admin): Logo/Thumbnail links im Terminblock
- Übersetzungen in allen 6 Sprachen
