feat(remote-support): consent-based remote session UI with audit log

Summary

Adds src/remote-support/ — TeamViewer/AnyDesk-inspired consent-first view/control demo with connection list and audit log. Mock local loopback only; no unauthorized access tooling.

DOCUMENTED vs LIVE

See src/remote-support/README.md — honest comparison; no fabricated LIVE access.

Test plan

• cd src/remote-support && npm ci && npm test && npm run build (4 tests)
• Smoke the UI
