feat(inbox): show research task logs inline in report detail pane

- Add signal_report field to Task type (FK from backend's sig/add-signal-report-task branch)
- Add signalReportId to TaskCreationInput and pass signal_report through API
- Add ReportTaskLogs component that finds the backend research task
  (origin_product: "signal_report") for a report and embeds TaskLogsPanel
- Show live-streaming task progress in the report detail pane during research
- Only matches backend research tasks, not user-created "Run cloud" tasks

Depends on PostHog/posthog sig/add-signal-report-task branch.
