Implement Generate Invoice

Browse Source 
<UserStory> PAY001: Generate Invoice </UserStory>

<Changes>
    1. Added Utility.h to project configuration for supporting invoice generation utilities.
    2. Updated Invoice model to use string-based keys for parts mapping instead of integer keys.
    3. Implemented PaymentManagementService::generateInvoice to aggregate labour cost, parts cost, and apply discounts.
    4. Integrated invoice creation with Factory to instantiate Invoice objects and persist them into datastore.
    5. Enhanced Enums with PaymentMode::NOTSET to handle default invoice state.
</Changes>

<Test>

 Acceptance Criteria:
 1. Invoice auto-generates for each service booking once jobs are completed.
 2. Invoice shows a clear breakdown of charges including labour cost, parts cost, discount, and total amount.

 Precondition:
  1. Service booking exists with at least one service and required inventory items.
  2. Datastore is available for storing invoices.
  3. Payment mode and status enums are properly configured.

 Steps:
  1. Complete all jobs in a service booking.
    - Verify that PaymentManagementService::generateInvoice is triggered.
  2. Check datastore for newly created invoice.
    - Verify that invoice contains booking ID, labour cost, parts cost, discount, and total amount.
  3. Inspect invoice details.
    - Verify that breakdown of charges is accurate and discount is applied correctly.
  4. Confirm invoice status.
    - Verify that invoice is created with PaymentMode::NOTSET and PaymentStatus::PENDING.
</Test>
