Changes

CORR-07: angular rate wraps RA deltas across 0/360, scales by cos(dec), uses hypot.
CORR-08: StateVector.to_ra_dec clamps asin input and handles zero radius; Kepler solver wraps mean anomaly, uses a stable initial guess, validates eccentricity, allows more iterations.

Tests

tests/test_orbit_propagator_fixes.py: RA wrap + declination scaling, asin round-off clamp, convergence at e=0.95.

Verification

Full suite with the new tests passes locally on this branch (25 existing + new tests, pytest on Windows, Python venv).
py_compile clean; ruff fatal-error lint (E9,F63,F7,F82) clean.
Does not touch files owned by open PRs Move Cesium token, API key and DB DSN to environment variables #1-Fix HIGH correctness bugs CORR-01..05 #5.

Drafted by Codex from the medium/low review findings; split and re-verified per branch.
