chore: remove phoenix_swagger

[jyeshe]

What

• Removes phoenix_swagger lib

Why

• Latest riverside requires poison 5.0 and phoenix_swagger up to 3.0.
• phoenix_swagger is not used anymore to generate swagger files, only to render the Swagger UI

[jyeshe]

@thepiwo @sborrazas a PR for the phoenix_swagger was submitted. If preferred for some reason to avoid the static assets there is also this option:

ae_mdw/mix.exs

Line 143 in e81a2b6

git: "https://github.com/jyeshe/phoenix_swagger.git", branch: "bump-poison"},

(to be removed if the static assets are merged)

Prefixed the /mdw when not present on the forwarding path (currently applies to dev, test and prod and after reorganizing the prod we might remove from dev and test).

do we really need to serve the swagger UI? as long as we expose the definitions any hosted UI can be used right? Maybe we can include an example for that in the docs
