Add Tests for Stateful Event Deletion Response in Queue Handling

[vikman90]

Parent Issue: #241

Description

The feature to exclude the event body when reporting a delete operation, implemented in PR #393, lacks adequate testing. To ensure its correct behavior, we need to add tests covering both the Inventory module and the core of the agent.

Requirements

1. Inventory Module Behavior
   • When the Inventory module pushes a stateful message into the Queue, it must insert an empty JSON object ({}) as data if metadata.operation is "delete".
2. Agent Core Behavior
   • When the core of the agent extracts a stateful message from the Queue, it must:
     • Transmit data + \n + metadata if data is not an empty object ({}).
     • Transmit only metadata if data is an empty object ({}).
