feat: agent-04 – Team-Dashboard für Manager/HR im Frontend angebunden

Das Backend liefert /dashboard/team (team_dashboard) bereits, die DashboardPage
lud aber nur /dashboard/me und /dashboard/company → Manager/HR sahen nur das
Mitarbeiter-Dashboard. Jetzt:

- Manager-Rollen (MANAGER/HR/COMPANY_ADMIN/SUPER_ADMIN) laden /dashboard/team.
- Neue Sektion "Team heute": KPIs (anwesend / abwesend / nicht eingestempelt /
  Mitarbeiterzahl), ausstehende Genehmigungen als Quick-Links, Team-Tabelle
  (Status-Badge, Einstempelzeit, Stunden heute).

Reine Frontend-Anbindung – Backend, Reports und Exports (PDF/CSV/XLSX) waren
bereits vollständig (24 Report-Tests grün).
