New "Dokumenten-Pruefung" tab in Compliance Agent:
- User adds multiple URLs with document type (DSI, AGB, Impressum, Cookie, Widerruf)
- Each document loaded via Playwright, accordions expanded, text extracted
- Checked against type-specific legal checklist
- Optional: Cookie banner check via checkbox
Checklisten-UX (solves "100% looks like nothing was checked"):
- All checks shown per document: green checkmark + matched text excerpt
- Red X for missing fields with legal reference
- Builds user trust: "9 Punkte geprueft, alle bestanden"
- Expandable per document with completeness bar
New checklists:
- Impressum: §5 TMG (6 fields: name, address, contact, register, VAT, representative)
- Cookie-Richtlinie: §25 TDDDG (5 fields: types, purposes, retention, third-party, opt-out)
Backend:
- POST /agent/doc-check — async with polling (same pattern as /scan)
- DocCheckResult includes checks[] with passed/failed + matched_text
- dsi_document_checker returns all_checks in SCORE finding
- Email report shows per-document checklist

Fundamental fix: scans now run asynchronously with progress polling.
Backend:
- POST /scan starts background task, returns scan_id immediately
- GET /scan/{scan_id} returns status + progress + result when done
- 7 progress steps shown: Website scan, DSI discovery, DSE analysis,
SOLL/IST comparison, corrections, report, email
- In-memory job store (dict with scan_id → status/result)
- No timeout limits on scan duration
Frontend:
- POST starts scan, receives scan_id
- Polls GET every 5 seconds (max 120 attempts = 10 min)
- Shows live progress message during scan
- Displays result when completed, error when failed
Proxy:
- POST timeout reduced to 30s (just starts the job)
- GET timeout 10s (just status check)
- No more 504/connection-dropped errors
