Changes:
- Refactored ServiceManagementService::updateJobStatus() to use tracked
job card references instead of raw pointers, ensuring consistent state
updates.
- Added proper null checks and error handling for current job retrieval
to prevent unexpected termination.
- Updated logic to mark tracked job records as MODIFIED when status
transitions occur (STARTED → IN_PROGRESS, IN_PROGRESS → COMPLETED).
- Simplified control flow and indentation for better readability and
maintainability.
Fixes#2076
