Review routes and ensure that there are no more navigation warnings around calling next more than once

As unveiled in the [following issue](https://github.com/AlmaLinux/build-system/issues/430) and resolved in [this PR](https://github.com/AlmaLinux/albs-frontend/pull/588), there might be some navigation in other places due to use of calling `next()` as part of promise handling in the routing process.

We should review albs-frontend's [routes.js](https://github.com/AlmaLinux/albs-frontend/blob/master/src/router/routes.js) and ensure that:
* We stop calling next, and pass it as a callback in the promise resolution process
* Several store/state dispatchers in `beforeEnter` should be wrapped into a Promise.all

After the update, we need to check that the navigation works as expected and that there are no more navigation warnings around.
