fix: update test_live_charts.py reference data to match corrected ephemeris

- Einstein: chiron Aries 0.00 -> Taurus 5.55, true_node 2.73 -> 1.48, MC 12.39 -> 9.07, ASC 8.90 -> 8.72
- Chaka Khan: chiron Aries 0.00 -> Capricornus 20.22, true_node 11.14 -> 9.73 (retro), MC 22.33 -> 17.45

Old reference data was captured from pre-upgrade ephemeris with house/chiron bugs.
New values match astro-charts.com and the current live server output.
