feat(ci): add weekly NX security audit workflow

[h0lybyte]

Summary

• New ci-nx-security.yml workflow running every Wednesday 06:00 UTC (+ manual dispatch)
• Aggregates security audits from 5 ecosystems: pnpm audit, cargo audit, pip-audit, CodeQL alerts, Dependabot alerts
• New scripts/nx-security-to-mdx.py generates both nx-security.mdx (Starlight dashboard page) and nx-security.json (structured data)
• Same patterns as existing ci-weekly-nx-report.yml: fork guard, arc-runner-set, auto-PR to dev

Output files

• apps/kbve/astro-kbve/src/content/docs/dashboard/nx-security.mdx — severity cards, ecosystem breakdown, tabbed detail per ecosystem
• apps/kbve/astro-kbve/public/data/nx/nx-security.json — structured JSON with normalized severity counts

Test plan

• Python script tested locally with mock data (findings + all-clear scenarios)
• --help flag works
• flake8 + autopep8 pass
• Trigger workflow_dispatch to verify end-to-end after merge
• Verify MDX renders on kbve.com/dashboard/nx-security/
