Merged PR 1159: Vehicle Service System v1.1.0.0

**New Features**

**Payment Confirmation Workflow**
- Added support for payment confirmation by administrators.

- Introduced a new PAID payment status.

- Implemented invoice confirmation flow from PAID → COMPLETED.

- Added invoice filtering based on payment status.

- Added admin menu option to confirm customer payments.

**Technician Job Status Workflow**
- Enhanced technician job management with multi-stage status updates.

- Added support for job status transitions:

- STARTED → IN_PROGRESS

- IN_PROGRESS → COMPLETED

- Added invoice generation and customer notification upon booking completion.

- Improved job visibility by displaying current job status.

**UI Improvements**
- Improved formatting and wording in the Technician Job Status workflow.

- Standardized status labels using "In Progress".

- Improved prompts, headings, and job selection messages.

- Enhanced readability of job listings.

**Bug Fixes**
- Fixed duplicate customer notifications when an assigned technician is removed.

- Prevented creation of duplicate usernames across all user states.

- Fixed authentication conflicts caused by reuse of deleted/disabled usernames.

- Improved booking cancellation handling for customer and technician removal scenarios.

- Updated cancellation logic to correctly handle bookings in IN_PROGRESS state.
