<UserStory> SER1798: Update Job Status </UserStory>

<Changes>
    1. Renamed Controller and ServiceManagementService methods from completeJob to updateJobStatus for clarity and flexibility.
    2. Enhanced ServiceManagementService::updateJobStatus to support transitions:
       - STARTED → INPROGRESS
       - INPROGRESS → COMPLETED (with invoice generation and customer notification).
    3. Added INPROGRESS state to ServiceJobStatus enum and updated string conversion utilities.
    4. Introduced filterJobCards helper to generalize job filtering by status.
    5. Updated TechnicianMenu to allow technicians to select job type (Started/Inprogress) and update status accordingly.
    6. Improved job display to show current status and truncated service names for readability.
</Changes>

<Test>

 Acceptance Criteria:
 1. Technician can select a job with status STARTED and update it to INPROGRESS.
 2. Technician can select a job with status INPROGRESS and update it to COMPLETED.
 3. Completed bookings automatically generate invoices and send notifications to customers.
 4. Job status updates are reflected in the technician’s job list and customer view.

 Precondition:
 1. Technician is logged into the system.
 2. Assigned job cards exist with valid statuses (STARTED or INPROGRESS).
 3. Datastore and payment service are available.

 Steps:
 1. Navigate to Technician menu and choose "Update Job Status".
    - Verify that the system prompts for job type selection (Started/Inprogress).
 2. Select a job card from the filtered list.
    - Verify that the job card details are displayed with status.
 3. Confirm update.
    - Verify that the job status changes correctly.
 4. For jobs updated to COMPLETED:
    - Verify that the booking status is updated, invoice is generated, and notification is sent.
</Test>
