Changes:
- Updated ServiceManagementService::createJobCard() to prevent duplicate
"Technician assigned" notifications when multiple job cards exist for
the same booking.
- Refined job card creation notification to include Job Card ID, Service
ID, and Booking ID for clearer technician communication.
- Corrected service booking cancellation notification formatting by
standardizing capitalization and improving message clarity.
- Improved service booking completion notification to explicitly mention
the booking ID and confirm invoice generation.
- Ensured consistent notification titles and messages across the
workflow for better user understanding.
Fixes#2114
