feat(runs): add runs pages, polling, autorefresh indicator, and scheduler fix

- add global runs page and per-scenario runs/run-detail pages
- run detail page polls every 1s until pass/fail, cleans up on unmount
- runs list pages poll every 10s with AutoRefreshIndicator (pulse on data load)
- fix scheduler: set run to pass after empty step loop to prevent stuck in_progress
- fix table header colors and link cell color for readability
- fix play button to navigate to the new run after creation
- fix package.json import paths in server for Docker build context
