feat: send command typed in container to API

- Modify the Dockerfile in the `server/quests/helloworld` directory to add a user and change the working directory
- Rename the file `server/quests/helloworld/entrypoint.sh` to `server/quests/helloworld/home/.bashrc`
- Modify the `server/src/config.js` file to add the `isProduction` flag
- Modify the `server/src/utils/docker.js` file to add a `HostConfig` option and bind a directory if not in production mode
- Modify the Dockerfile to add an argument `DOCKER_GID` and create a group and user with the specified `DOCKER_GID`
- Add a new Dockerfile.dev file with the same modifications as the Dockerfile
- Add a new file `inspect.sh`
- Modify the `server/src/client.js` file to use the `API_ENDPOINT` variable instead of a hardcoded URL
