Integrate Incentives API with Midas Core

[utkarsh11616]

Integrate the Incentives API into Midas Core so that after a transaction is validated, it is posted to the Incentives API endpoint (http://localhost:8080/incentive) as a JSON serialized Transaction object. The API will respond with an Incentive object containing the "amount" field. This incentive amount should be recorded alongside the transaction and added to the recipient's balance, but not deducted from the sender's balance.

Requirements:

• Use Spring RestTemplate to POST validated transactions to the Incentives API
• Ensure the Transaction object is properly serialized (Spring can handle serialization)
• Update the Transaction model to include an incentive field
• When modifying balances, add incentive to recipient; do not deduct from sender
• Ensure robust error handling for API communication
• Document integration steps and expected behaviors
• Run "TaskFourTests" after integration and verify user balances

API Contract:

• Endpoint: POST http://localhost:8080/incentive
• Request: Transaction object (JSON)
• Response: Incentive object (JSON, field: amount >= 0)

Edge Cases:

• Handle failed API calls gracefully
• Ensure incentives are always >= 0
• Incentive must be recorded correctly for auditing purposes

Testing:

• Use the debugger to verify the final balance of user "wilbur" after processing all transactions.
• Submit the integer balance as required.

• Show API into Midas Core after transaction.
• Show JSON as a serialised transaction object.
• API will respond as an incentive object containing the "amount".
• Incentives should be recorded alongside the transaction and added to the recipeints balance.
• Not deducted from the sender's balance.
