Handle broadcast IDs in client details retrieval

Add a check for broadcast node IDs (4294967295 and 1) in the `_get_client_details` method to return a predefined `ClientDetails` instance. This prevents unnecessary database queries for broadcast IDs and ensures consistent handling of these special cases.
