feat(core+frontend): Firmendaten im Admin + PDF-Fusszeile

Backend:
- GET/POST /settings/company (Redis-Key platform_company_settings)
  Felder: name, street, postalCode, city, phone, email, website
- ProfileExportService: RedisService injiziert, laedt Firmendaten vor PDF-Erzeugung
- PDF-Footer: Trennlinie + kompakte Zeile mit allen Firmendaten auf jeder Seite
  (bufferPages=true, switchToPage-Loop vor doc.end())

Frontend:
- AdminCompanyPage: Formular mit Vorschau der Fusszeile
- AdminLayout: neuer Tab 'Firmendaten'
- App.tsx: Route /admin/company
