feat(ui): alle Filter als Checkbox-Gruppen statt Dropdowns + Aufgaben-Filter

- Neuer wiederverwendbarer Helper renderFilterGroup (app.js) + filter-bar-CSS.
  Mehrfachauswahl per Checkbox, nichts angehakt = alle, Gold-Akzent.
- Quellenliste: Herkunft/Typ/Status/Kategorie/Sprache als Checkbox-Leiste
  unter der Action-Bar. Checkbox-Spalte + Bulk-Promote erscheinen, wenn der
  Herkunfts-Filter ausschliesslich auf Kundenquellen steht.
- Aufgaben ist jetzt filterbar: Vorschlagstyp und Prioritaet fuer die
  Vorschlags-Tabelle, Konfidenz-Stufen (ab 85, 70 bis 85, 50 bis 70,
  unter 50 Prozent) fuer die Klassifikations-Karten. Das alte
  Mindest-Konfidenz-Dropdown entfaellt, die Queue laedt einmal komplett
  und filtert clientseitig.
- Audit-Log: Aktion/Ressource/Admin als Checkbox-Gruppen, Backend
  akzeptiert dafuer kommagetrennte Mehrfachwerte (IN-Filter,
  Einzelwert bleibt kompatibel). Ressourcen-ID und Datumsfelder bleiben
  Eingabefelder.
