fix: use getDataDir() for CronService storage path (#139)

Fix path mismatch between CLI and CronService that caused cron jobs
created via CLI to never be picked up by the running service.

- CLI uses getDataDir() for cron-jobs.json
- CronService was overriding with workingDir path
- Now both use getDataDir() (defaults to cwd or Railway volume)

Fixes #135
