Refactor Python API structure and enhance backend command handling

Major refactor of the Python API: moved modules into subdirectories, replaced app.py with api.py, and added new audio and utility modules. Backend C++ code now tracks command execution results, exposes them via the API, and improves command result handling. Also includes updates to the SRS audio handler, random string generation, and VSCode launch configurations.
