feat: Rechtsseiten (Impressum/AGB/Datenschutz) + Footer + Menü-Fix

- content/impressum.md, agb.md, datenschutz.md (Einzelfirma Karim, CH-Recht,
  [PLATZHALTER] für Adresse/UID/Datum — vor Produktiv juristisch prüfen)
- custom/footer.html: 4-spaltiger Footer (Produkt/Ressourcen/Rechtliches/
  Hosting-CH-Hinweis) + Styling
- hugo.yaml: 'Anmelden' im Menü; doppeltes params bei Gitea entfernt
  (icon:github wurde von type:search überschrieben → Icon war kaputt)
