fix: skip failing nodes when gathering porcess info (#6412)

Browse Source 
* fix/process-manager-skip-fail-nodes:
 - **Enhance Error Handling in `process_manager.rs`:**
   Improved error handling by adding a warning log for failing nodes in the `list_process` method. This ensures that the process listing continues even if some nodes fail to respond.

 - **Add Error Type Import in `process_manager.rs`:**
   Included the `Error` type from the `error` module to handle errors more effectively within the `ProcessManager` implementation.

* fix/process-manager-skip-fail-nodes:
 **Enhancements to Debugging and Trait Implementation**

 - **`process_manager.rs`**: Improved logging by adding more detailed error messages when skipping failing nodes.
 - **`selector.rs`**: Enhanced the `FrontendClient` trait by adding the `Debug` trait bound to improve debugging capabilities.
