macOS Agent: Incorrect gRPC service prevents events from being sent

[osmontero]

Description

The UTMStack macOS Agent can be installed correctly, but it is not sending events to UTMStack. This is due to the agent attempting to communicate with an incorrect gRPC service.

Expected Behavior

The macOS Agent should use the correct gRPC service to send logs and events to the UTMStack Event Processor.

Actual Behavior

The agent installs successfully but fails to deliver events because of a mismatch in the gRPC service definition or endpoint it is targeting.

Steps to Reproduce

1. Install the UTMStack macOS Agent on a macOS machine.
2. Configure it to point to a UTMStack instance.
3. Observe that no events are received by the UTMStack instance, and check agent logs for gRPC communication errors.

Potential Cause

The agent might be using an outdated or incorrect gRPC service name/method that does not match the current implementation in the Event Processor (e.g., mismatching the Engine service or its Input method).
