ref(insights): group all module routes under one constant

[DominikB2014]

This PR groups all module routes under one moduleRoutes constant. And then this constant is used within the frontend,backend,mobile and ai domain view routes. There's two motivations behind this

1. Simplifies adding new modules, you only have to add routes in one place
2. We have had a couple internal and external feedback, that certain modules belong in certain domains. For example some users requested http module should be under mobile as well. And we may add the assets module to mobile at some point too. This PR means we never have to worry about adding new routes when moving modules to new domains, we just have to update the header tabs to link to the module.

One drawback is that there will be some unused routes, but I don't see this being a problem, and it simplifies things a little.
