Add documentation for modules and runtime instructions

- Created detailed documentation for the device_manager, model, model_extra, osc, overlay, overlay_image, transcription, translation, transliteration, utils, watchdog, and websocket modules.
- Added a comprehensive run events payloads document outlining the payloads sent during various run events in the controller.
- Included runtime instructions and dependencies for setting up the project in a Windows environment.
- Introduced a mypy configuration file to manage type checking and ignore errors in specific modules temporarily.
