fix(sources): Typ-Filter in der Fall-Quellenuebersicht immer anzeigen

Die Filter-Chips wurden nur eingeblendet, wenn ein Fall Telegram- oder
X-Quellen hatte. Bei reinen Web-Faellen (z.B. in der Org jp_demo) fehlte
die Filterleiste damit komplett. Sie wird jetzt immer angezeigt, sobald
Quellen vorhanden sind, und zeigt zugleich, welche Quellentypen der Fall
enthaelt.
