feat(einricht): Einrichtungen miteinander verknüpfen

Neue Tabelle organigramm_einricht_link für n:m-Beziehungen zwischen
Einrichtungen. In der Bearbeitungskarte gibt es jetzt ein
Mehrfachauswahlfeld (Semantic UI Dropdown) um verwandte Einrichtungen
zu verknüpfen (z.B. alle HzE-Einrichtungen unter der Gruppe HzE).

- Neue Funktion saveLinkedEinrichts() speichert die Verknüpfungen
- Cardform lädt bestehende Links als Vorauswahl (Strings, kein int-Cast
  damit Semantic UI den data-value-Vergleich korrekt auflöst)
- onChange-Handler + explizite hidden-input-Befüllung sichern
  zuverlässige Übergabe beim Formular-Submit
