fix(athena): remove dead temperature/permission fields from council launch pipeline

LaunchInput.temperature and LaunchInput.permission were accepted and
passed through the council orchestrator but never forwarded to the
actual promptAsync API call (SDK doesn't support per-request temperature
or permission). Remove the dead fields, the unused AthenaConfig
interface, and update tests/docs/schema accordingly.
