Risk score now pulls from multiple threat intel sources instead of
only AI/CVSS data:
- EPSS (FIRST.org) — probability of exploitation in next 30 days
- CISA KEV — known actively exploited vulnerabilities (with ransomware flag)
- Existing Wazuh exploit flags as fallback
Adds DB columns (epss_score, epss_percentile, kev_listed, kev_*,
enrichment_sources, enrichment_updated_at), an enrichment_service
with cached KEV catalog (24h TTL in settings table) and batched
EPSS lookups, manual + bulk + KEV-refresh endpoints, automatic
enrichment after Wazuh sync, and a daily scheduler job to refresh
scores.
Frontend gets KEV badges, EPSS column with percentile, KEV-only +
EPSS-min filters, a "Refresh Threat Intel" button, and a priority
score breakdown card on the detail page.
