Implement review fixes

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
