feat(wiki): Beitragsliste für Betriebsrat-Nutzer auf zugängliche Kategorien filtern

BR-Nutzer (r-wiki-br ohne r-wiki) sehen in der Beitragsliste und im
Kategorie-Dropdown nur Beiträge und Kategorien, die ihren freigegebenen
Kategorien (betriebsrat_editable=1 + alle Nachfahren per BFS) zugeordnet sind.

Der Filter wird server-seitig in post_listform.php berechnet und als Parameter
an den Ajax-Endpunkt übergeben, da get_permission_state() im Ajax-Kontext
nicht verfügbar ist.
