fix(web): CronPage crash when rendering schedule object

The cron API returns schedule as {kind, expr, display} object but
CronPage.tsx rendered it directly as a React child, crashing with
'Objects are not valid as a React child'.

- Update CronJob interface in api.ts to match actual API response
- Use schedule_display (string) instead of schedule (object)
- Use state instead of status for job state
- Use last_error instead of error for error display
