As a supervisor using the 1097 application, I want an API to fetch the count of calls already allocated to agents specifically for Level 3, So that I can view the distribution of Level 3 allocated calls and re-allocate them effectively if needed.

Acceptance Criteria:

API Functionality:
The API should fetch the total count of calls allocated to each agent for Level 3 only.

Request Parameters:
No input parameters are required as this API is specific to Level 3.

Response:
The API should return the following details:
Agent ID: Unique identifier for the agent.
Allocated Call Count: Number of calls allocated to the agent for Level 3.

Validation Rules:
The API should ensure that only Level 3 data is fetched.

Error Handling:
The API should return appropriate error messages if:
No Level 3 data is found for any agent.

Audit and Logging:
All API requests and responses should be logged for audit purposes, including the supervisor's request and data fetched.

Performance:
The API should be optimized to handle large datasets and return results quickly.
API Endpoint:
GET /api/v1/allocated-call-count/level3

Sample Request:
No parameters required.
