Autoload issue with ImpressionistController (#2)

Instead of depending on autoload to bring in the ImpressionistController constant, we manually bring it with a call to require and just move that file to lib. Prior to this, Rails would emit a warning on startup about needing to use autoload durning an initializer like this, letting us know that a future version of Rails will error. This should hopefully remove that error and still allow these controller mixins to be available. Note that Rails 7.1 will eventually be a future blocker here. PS. This is the recommended approach by Xavier here: charlotte-ruby#305 Co-authored-by: stefannibrasil <[email protected]>
