fix: Import-500 bei doppelten UIDs, Picker-UI & Settings-URL-State

- Import: Dedupe doppelter UIDs innerhalb der Datei (Nextcloud exportiert wiederkehrende Termine als mehrere VEVENTs gleicher UID) -> kein UNIQUE-constraint-500 mehr; Commit abgesichert. Test ergaenzt (15 gruen). - Picker (Gruppen-Sichtbarkeit + Mitglieder): als <div>-Zeilen statt <label>, damit die globale ".form-group label"-Uppercase/Grau-Regel das Layout nicht mehr zerschiesst. Saubere .pick-row-Optik (Checkbox/Radio links, Name links). - Einstellungen haben jetzt eigenen URL-State (#...&settings=1): Reload/Cache- leeren bleibt in den Einstellungen statt zur Kalenderansicht zu springen. - Version v27.
