Improve Hanami::View inspect outputs

[jodosha]

@parndt raised this:

I see this using better errors sometimes

(Object too large. Modify
Hanami::View::Rendering#inspect or adjust
BetterErrors.maximum_variable_inspect_size if you need to see it.)

We need an assessment of all of our user-facing objects (Actions, Views, Router, etc...) to understand:

1. How does the #inspect output look, and how can it be simplified?
2. Are we passing too many dependencies? Can we simplify them?
   a. Example: instead of passing the entire configuration, try to pass only the few settings needed.
