Task 454: EP03 Navigation Error Region Visualization

Status: DONE

Summary

Added 3 visualizations to EP03 report for navigation error analysis:

1. Log-scale bar chart: Error scale comparison — ±18 km precision vs 14.36M km error vs Uranus Hill sphere (51.8M km) vs remaining distance (670M km). Log scale reveals the 5-order-of-magnitude gap between required precision and actual error.
2. Angle sensitivity chart: How miss distance at Uranus varies with angular discrepancy (0°–5°). Shows 1.23° (in-story value) produces 1,436万km error within Hill sphere, while 5° exceeds Hill sphere. Includes Hill sphere reference line.
3. Time evolution chart: Lateral drift over 66 hours if wrong navigation choice was made. At 64.4 km/s lateral velocity (3,000 × sin(1.23°)), drift reaches 23万km in 1 hour and 1,436万km at arrival — showing early detection is critical but impossible without independent reference.

Charts integrated into existing timeseries-charts: block. 7 content validation tests added.
