Mitarbeiter bearbeiten: Button zum Ändern bestehender Daten

Pro Mitarbeiter-Zeile ein "Bearbeiten"-Button, der die Zeile in ein
Inline-Formular umschaltet (alle Felder, insbesondere die
Wochenkapazität). "Speichern" nutzt den bereits vorhandenen
store.updateEmployee/PUT-Endpoint, "Abbrechen" verwirft die Änderung.
