UI-Verbesserungen: Favicon, Tab-Titel, Kalender umbenennen, Avatar-Crop, Farbpalette

- SVG-Favicon hinzugefügt - Dynamischer Tab-Titel (z.B. "Calendarr - März 2026") - Kalender per Doppelklick umbenennen (Backend + Frontend) - Avatar-Anzeige im Topbar gefixt (onerror Fallback, robustes Laden) - Avatar-Upload mit Cropper.js Bildausschnitt-Wahl - Avatar-Limit auf 5 MB erhöht, Thumbnail auf 512px - Farbpalette statt nativem Color-Picker für Kalenderfarben
