Issue Title: Implement Job Management Functionality

Issue Description:

As a client, I want to manage my job listings effectively so that I can view, update, or delete my jobs as needed. This functionality should provide endpoints for clients to interact with their job postings.

Tasks:

1. Get All Jobs:

   • Create an endpoint in the JobController to retrieve all job listings posted by the authenticated client.
   • Implement pagination to limit the number of jobs returned in a single request.

2. Get Specific Job by ID:

   • Create an endpoint to fetch details of a specific job posted by the authenticated client using its job ID.

3. Update Job:

   • Create an endpoint to allow clients to update the details of their job postings.
   • Ensure that only the client who created the job can update it.

4. Delete Job:

   • Create an endpoint to allow clients to delete their job postings.
   • Implement checks to ensure that only the client who created the job can delete it.

Acceptance Criteria:

• Get All Jobs:

  • Clients should be able to make a GET request to /jobs to retrieve their job listings.
  • Return 200 OK with a list of jobs or 204 No Content if no jobs are found.

• Get Specific Job by ID:

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

• Update Job:

  • Clients should be able to make a PUT request to /jobs/{jobId} to update their job details.
  • Return 200 OK if the update is successful or 400 Bad Request if invalid data is provided.

• Delete Job:

  • Clients should be able to make a DELETE request to /jobs/{jobId} to delete their job postings.
  • Return 204 No Content if the deletion is successful or 404 Not Found if the job does not exist.
