fix(tests): fix failing unit tests

- Fix beadWorkspaceScanner.test.ts: make beforeEach async to use top-level await
- Fix parser.real-logs.integration.test.ts: change sequence test to non-decreasing (real logs have duplicate sequences)
- Fix FleetSummaryBar.test.tsx: correct expected separator count from 5 to 4

All 2484 tests now pass (was 89 failed due to wrong Node.js version + 3 test bugs).
