User actions should be in the Domain namespace instead of the Application namespace

[kanevbg]

In my opinion these are better suited being in the Domain namespace, as they're implementations are domain-specific. Do you agree?

An action class is a "controller", more precisely a single action controller, which only handles the HTTP request/response-specific tasks. It therefore does not belongs to the Domain namespace.

I saw some articles putting an additionnal layer for API/Controller/Views/etc. whatever that comes from the outside. a "Presentation" layer if I remember.

If anything needs to change, the Action (Controller) should be in Presentation layer and the handler of the action in the Application layer.
