The browser router doesn't seem to work inside cockpit, switching
to the hashrouter resolves this.

Switch the useFlag usage to the stub function defined in the
`useGetEnvironment` utility

We need to check for the on-prem use case

We were making a call to a dead endpoint to get the architectures.
Instead, create a custom query function to return the list of architectures
and image types.

Create a get blueprint endpoint for the on-prem store.

Create the boilerplate function for getting the Oscap profiles. We will
need to make a call to the `oscap` binary to get this information. So
we will leave it empty for now.

Create a helper hook for RTK prefetch queries. This wrapper function
is needed since the imagebuilderApi and cockpitApi aren't at parity
yet.

Currently, the wizard still needs some of the other stores. If we
omit them, the wizard fails to launch

Including an image in the on prem version inside cockpit is not
trivial. We need a bit of a workaround to get the various target icons
showing on the on-prem version in cockpit.

For a start, we will disable custom repositories and the OpenSCAP steps
for the on-prem version of the frontend.

Subject says it all

Add a stub function for the `os-release` package from cockpit.

Add a hook that gets the host distro for the on-prem frontend. If there
is an issue we will fallback to the default. For the service we also
just use the default distro.
