What was done?

• Created TransactionController with endpoints for creating, retrieving (all and by ID), updating, and deleting transactions.
• Implemented TransactionService with business logic and integration with AccountService and CategoryService.
• Added DTOs: CreateTransactionDTO, TransactionUpdateDTO, and TransactionResponseDTO.
• Created TransactionMapper using MapStruct for entity-DTO conversion.
• Added TransactionRepository using Spring Data JPA.
• Updated SwaggerConfig to include JWT bearer authentication for API documentation.

Tests

• I tested the new feature/fix locally.
• Write the unit tests.

How to Test

1. Start the application.
2. Use Swagger UI or Postman to test the following endpoints:
   • POST /transaction/create — Create a new transaction.
   • GET /transaction — Retrieve all transactions.
   • GET /transaction/{id} — Retrieve a transaction by ID.
   • PUT /transaction/{id} — Update an existing transaction.
   • DELETE /transaction/{id} — Delete a transaction.
3. Check the Swagger UI to verify JWT authentication is required and functioning.

Dependencies

This implementation depends on working AccountService and CategoryService, as they are used in transaction creation and updates.
Also, ensure JWT tokens are configured to test secured endpoints in Swagger.
