Snapshot/history: "Snapshot speichern" + a version list (status, date, coverage)
you can click through — makes the CRA Art. 13 running system visible (backend
endpoints already live). Measure-class: each finding shows a remediation-class
badge from its CRA evidence_type ("Code-nah" = scan-locatable, code-fix in the
ticket possible; otherwise Prozess/Doku), and the measures section is relabelled
as the Sollzustand (process/build) — no auto-fix buttons on process measures.
Backend: MappedFinding now carries evidence_type.
