Fixed delete Job and update user status.

[rohity20]

Fixed #1

The issue in the code is that when a person is selected for a job and the recruiter deletes that job, the code does not update the person's job status, leaving them unable to apply for other jobs.
I have provided an API function for handling job deletion. It starts by checking if the authenticated user is a "recruiter" and, if not, returns a 401 Unauthorised response. If the user is a recruiter, it attempts to delete a job with the specified ID belonging to that user. If the job is successfully deleted, it updates the status of related applications to "deleted" and responds with a success message. In case of any errors, it returns a 400 Bad Request response with the error details
