Hide secrets when logging emmiter event through framework logger

[jezekra1]

If you log the event to console, it will contain the creator property which contains llm instance with client and its credentials. This is a problem if logs from the application with bee-agent-framework are collected to a monitoring stack where other people than the admin of the application have access.

We tell the users to do it here:

bee-agent-framework/examples/agents/bee.ts

Line 107 in 65b7da4

// event,

To Reproduce
Uncomment the block of code in the bee.ts and run the example (tested with ibm-vllm adapter). You will see credentials in console.

Expected behavior
Filter all sensitive information when using the framework logger.
