feat(db): backfill, DB-backed web scans, firewall snapshot view (R001/S001/F001)
- R001: app/db/backfill.py imports git-history blocklist -> ledger, firewall
snapshots, and per-source requests.csv (idempotent; ran live migrating 705
historical blocklist entries).
- S001: web_scan.latest_scans() now merges SQLite 'scans' records so the
dashboard surfaces CLI/restart scans (_db_scans).
- F001: /api/firewall/snapshots + 'Snapshot history' panel; added
recent_firewall_snapshots() query with entry counts.
