fix(cron): pass 'id' instead of 'jobId' to gateway

The cron tool was passing { jobId } to the gateway for update/remove/run/runs
actions, but the gateway protocol schema expects { id }. This caused validation
errors when trying to update or remove cron jobs via the tool.

Fixes the parameter name while keeping the external tool API unchanged (still
accepts 'jobId' from callers).
