Fix RabbitMQ log forwarder EventId names in structured logs

[alirezafzali]

Description

RabbitMQ's EventSource uses event names "Info", "Warn", and "Error" that mirror log level. RabbitMQEventSourceLogForwarder was passing those into ILogger as EventId.Name, so the Aspire dashboard structured log UI showed misleading event names (e.g. "Error") instead of leaving the event name unset.

This change forwards only the numeric RabbitMQ event id (1 / 2 / 3) and omits the level-like name. Log level continues to come from LogLevel as before.

Duplicate log message text in structured logs was already addressed in #6827; this completes the remaining part of #2967.

Changes:

• RabbitMQEventSourceLogForwarder.cs: use new EventId(eventData.EventId) instead of including eventData.EventName
• AspireRabbitMQLoggingTests.cs: add ForwardsEventIdWithoutLevelName regression test

Dependencies: None

Fixes #2967

Note

Copilot was unable to run its full agentic suite in this review.

This PR adjusts RabbitMQ EventSource log forwarding to avoid populating EventId.Name with the EventSource level name, and adds a regression test to validate that behavior.

Changes:

• Stop passing eventData.EventName when constructing EventId during EventSource forwarding.
• Extend the test logger to record EventId values.
• Add a new unit test asserting EventId.Id is forwarded while EventId.Name remains empty.

tests/Aspire.RabbitMQ.Client.Tests/AspireRabbitMQLoggingTests.cs	Adds a test for EventId name suppression; updates test logger to capture EventId.
src/Components/Aspire.RabbitMQ.Client/RabbitMQEventSourceLogForwarder.cs	Changes EventId construction to omit Name, preventing level name being forwarded.

The other unit tests in this file don’t wait after Log*. EventSource forwarding is synchronous once the listener is started. Happy to restructure if maintainers prefer a different pattern.
