feat(cra): Management-Fortschritts-Ansicht (Ticket-Status-Readback)

Liest den Lebenszyklus jedes Befunds (status + tracker_issue_url) aus dem
Scanner zurück und rollt ihn zu einem Management-Bild auf: % erledigt,
4-Phasen (offen/in Arbeit/erledigt/ausgeschlossen), offenes Restrisiko nach
Schweregrad, Fortschritt je CRA-Anforderung und eine Aufgaben-/Ticket-Tabelle
mit Jira-Link. Neuer Endpoint GET/POST /api/v1/cra/progress (dünn → Service
cra_progress, rein deterministisch, kein /assess-Schema-Drift). Frontend:
ProgressView in Ebene 1 (CRACyberView), live je Scanner-Repo, sonst Demo-Status.
