fix(api): correct HTTP endpoint URLs for live testing

- /api/run-tests → /api/live-testing/run
- /api/test-policy → /api/live-testing/policy
- /api/toggle-live-testing → /api/live-testing/toggle
- Add test state recovery on SSE connect via /api/live-testing/status
- Fix decode_event_data call (was referencing nonexistent sse_parser method)
