feat(privacy): scan ingested sources for customer-identifying data

Detection-only scan (internal/privacy) attached to every AnalysisResult:
a customer-domain guess plus a findings list (category, file, line, match,
hint), ported from the KB grep playbook. Runs on archive uploads and the
serialized Redfish tree; gated by LOGPILE_PRIVACY_SCAN (default on).

Surfaced at GET /api/privacy-scan, in the "Customer data" UI panel, and as
privacy_report.json in the raw-export bundle. IP policy keeps RFC1918 and
example ranges out of findings; allowlist covers standards-body and vendor
infrastructure domains. No customer tokens in the repo. See ADL-066 and
bible-local/docs/privacy-scan.md.
