feat: IODA fallback, UCDP timeout fix, PDF export, 18 tests

- infrastructure.py: Add IODA (Georgia Tech) as fallback when Cloudflare
  Radar returns 403 (no API token). Internet outage data now available
  without CLOUDFLARE_API_TOKEN.
- conflict.py: Increase UCDP GED API timeout from 15s to 30s to handle
  slow responses from ucdpapi.pcr.uu.se.
- dashboard/app.py: Add /api/report/pdf endpoint for PDF daily brief
  export via weasyprint (optional dependency).
- pyproject.toml: Add dashboard + pdf optional deps, intel-dashboard
  script entry point, update description for 55 tools.
- tests: Add 11 new tests covering health, sanctions, elections, shipping,
  social, nuclear, infrastructure (IODA fallback + cable health), and
  UCDP conflict. Fix cross-loop asyncio lock issue in conftest.
- Total: 50 tests passing, 55 tools verified.
