Erlaube keinen Protokollauszug, wenn keine Berechtigung auf Zielformular

Dies verhindert Zugriff auf den Protokollauszug beliebiger MTB-Formulare durch
"Erraten" von IDs.

Liegt keine Berechtigung für das Therapieplan-Formular (mit gegebener ID) vor,
können auch keine referenzierten MTB-Formulare abgerufen und deren Inhalt für
den Protokollauszug verwendet werden.
