feat(cron): set default enabled state for cron jobs

- Added logic to default the `enabled` property to `true` if not explicitly set as a boolean in the cron job input.
- Updated job creation and store functions to ensure consistent handling of the `enabled` state across the application.
- Enhanced input normalization to improve job configuration reliability.

This update ensures that cron jobs are enabled by default, enhancing user experience and reducing potential misconfigurations.
