feat(tests): remove Time Log, move Tempo sync to Phase Timeline

- Remove WorklogTimeline (manual time log) from test detail page
- TestPhaseTimeline now accepts testId, fetches its own worklogs,
  and shows Tempo sync status on the Red Team Execution row:
    • green badge if already synced (with worklog ID tooltip)
    • 'Sync to Tempo' button (blue) if not yet synced
- Add POST /tests/{id}/sync-tempo backend endpoint for manual sync:
  finds unsynced red_team_execution worklogs and pushes them to Tempo
