Separate config file logic for the server and the client

- The client now read the config file from the home user directory (.config/Gordon)
- Create the file if not exist
- If BackendURL and GordonToken are not present in the config file,  a prompt will ask the user to enter them
- Switch from ServerApp to ClientApp in main.go
- Add BackendURL to HttpConfig struct in app.go
- Remove GenerateAPIURL function, use BackendURL directly in http.go
