<UserStory> SER005: Update Service Status </UserStory>

<Changes>
    1. Integrated Controller with ServiceManagementService to support job completion workflow.
    2. Implemented ServiceManagementService::completeJob with validation for technician assignment, job existence, and status transition.
    3. Enhanced TechnicianMenu with job selection helper to display assigned jobs, allow index-based selection, and handle invalid choices.
    4. Updated TechnicianMenu::completeJob to mark job as completed via Controller and provide user feedback.
    5. Added logic to check if all jobs in a booking are completed, triggering invoice generation and customer notification.
</Changes>

<Test>

 Acceptance Criteria:
 1. Status updates are visible to customers immediately after technician marks job as completed.

 Precondition:
  1. Technician is logged into the system.
  2. At least one active job card is assigned to the technician.
  3. Datastore contains valid service bookings linked to jobs.

 Steps:
  1. Navigate to Technician menu and choose "Complete Job".
    - Verify that the system lists active jobs with index-based selection.
  2. Select a job card by index.
    - Verify that the job status changes from STARTED to COMPLETED.
  3. Check customer view.
    - Verify that the updated status is reflected in the customer’s booking history.
  4. If all jobs in the booking are completed:
    - Verify that an invoice is generated and a notification is sent to the customer.
</Test>
