update(bump-basic): plotly — comprehensive quality review (#4333)

## Summary

Updated **plotly** implementation for **bump-basic**.

### Changes
- Switched to F1 driver standings data (6 drivers, 8 races)
- Changed to per-driver color mapping dict for clearer code
- Better data with more rank crossovers
- Quality self-assessment: 93/100

## Test Plan

- [x] Preview images uploaded to GCS staging
- [x] Implementation file passes ruff format/check
- [x] Metadata YAML updated with current versions
- [ ] Automated review triggered
