fix(chart): skip unused synastry overview and doomed report subprocesses

Synastry charts now skip the unused external overview and run together. Reports skip PyJHora subprocesses when that library is missing, and a full heavy-compute slot logs which paths hold it. Splitting quotas stays a simulation.

Gate, growth, and report pytest passed, as did the frontend route tests, tsc, lint, and the A/B script.
