Module tasks + knowledgecenter_update aus Kundenprojekt übernehmen (bereinigt)

Beide Module wurden aus einem anderen Kundenprojekt kopiert und bereinigt:

Knowledgecenter:
- Bild-Cache (1.985 Dateien) geleert, Ordnerstruktur mit .gitkeep behalten
- Files-Gallery-Lizenzschlüssel entfernt (config.php)
- Kundenspezifische Kategorien gelöscht: Teil I/II/III QM-Struktur,
  nummerierte QM-Kapitel, Gremien (Präsidium/Finanzausschuss/Landesausschuss),
  Sitzungsservice-Serie, Protokoll-Abteilungen, Testeinträge
- 56 generische Kategorien bleiben (Downloads, Onboarding, Personalthemen …)

Tasks:
- Alle Betriebsdaten gelöscht (114 Tasks, 914 Submissions, 579 Assignments)
- Task-Definitionen und Verlinkungen geleert
- Kategoriestruktur bleibt (Allgemein, IT, Personal, Buchhaltung …)
