feat: measurement workflow improvements and recipe update-in-place

- Auto-advance to next task after completing all subtask measurements
- 1s pause between measurements to show pass/fail/warning result
- Colored marker strip (green/red/amber) based on measurement status
- Replace duplicate measurements instead of appending (fixes progress bar)
- Add Task column and Date/Time column to measurement summary table
- Enrich summary with task_info for each measurement
- Update-in-place for recipe versions without measurements (no copy-on-write)
- Dark theme improvements and navbar cleanup
- Server config: ignore extra env vars
