The card titled "SBOM" was displaying contribution type counts (FR/BR/EP/UPR)
which is unrelated to SBOM data. Added a sbomSnapState generator that fetches
/sbom/snapshots/ and shows: total tracked packages (sum of entry_count across
all snapshots), repos tracked, and copyleft risk count from the existing
licence_risk_count in the summary. Card turns orange if licenceRisk > 0.
Resolves suggestion b6775727.
