Issue Title: Implement Job Status Management Functionality

Issue Description:

As a client, I want to manage the status of my job postings so that I can track the progress of each job and update their statuses accordingly. This functionality should allow clients to change the status of their jobs based on their current state.

Tasks:

1. Update Job Status:

   • Create an endpoint in the JobController to allow clients to update the status of their job postings.
   • The status should be limited to the following options:
     • Open
     • In Progress
     • Completed
     • Cancelled

2. Get Job Status:

   • Create an endpoint to retrieve the current status of a specific job based on the job ID.

Acceptance Criteria:

• Update Job Status:

  • Clients should be able to make a PUT request to /jobs/{jobId}/status to update the job status.
  • Return 200 OK if the update is successful or 404 Not Found if the job does not exist.
  • Return 400 Bad Request if the provided status is invalid.

• Get Job Status:

  • Clients should be able to make a GET request to /jobs/{jobId}/status to retrieve the current status of the job.
  • Return 200 OK with the job status or 404 Not Found if the job does not exist.

Endpoint Specifications:

• Update Job Status:

  • Method: PUT
  • URL: /jobs/{jobId}/status
  • Request Body Example:

    {
      "status": "Completed"
    }

• Get Job Status:
