feat(hardware): initial hardware documentation, 3D models, and ESP32 client code

- Add initial versions of hardware bills of materials (BOM v1-v4), shopping lists, plan, and assembly guides. - Add STL models for 3D-printing the 1/27 scale OpenRC F1 car parts. - Add Blender 3D project files (.blend) and camera renders of the car design iterations. - Add ESP32 client firmware source (client.ino) for handling video streaming and car controls. - Ignore Blender backup files (*.blend1, *.blend2) and IDE directories.
