Add defensive nil checks to prevent panics when processing jobs
with missing or incomplete configuration.
Changes:
- Add nil check for job.Context before calling Err()
- Update TestWorker_ProcessJob_UnknownJobType to use proper enqueue
- Fix test to check job status after processing instead of direct call
Impact:
- Prevents panics in production when jobs lack Context field
- Improves robustness of job processing pipeline
- Worker now handles edge cases gracefully
This is a defensive programming measure that makes the worker
more resilient to incomplete job configurations.
