Separate CLI cmd from server cmd commands

[harveysanders]

Description

Now one can run the application via the CLI or straight binary. The CLI allows the user to set configuration from a series of prompts. The server application use env vars for configuration.

Additionally, the application had a few bugs and would not start:

panic: token client must not be nil

Fix here

panic: chi: all middlewares must be defined before routes on a mux

Fix here
