- PR #107971: fix(cron): guard reasoning_config against Pydantic models from v0.17 jobs.json

A bug introduced around v0.21 causes RuntimeError when code calls model_dump on plain dict objects instead of Pydantic models, breaking cron jobs. Two fixes address this by guarding against the error in the agent and cron reasoning_config paths.
