Fetch group labels after group selection

See merge request gitlab-org/gitlab!18616

Moves the request for group labels so that
it occurs after a group has been selected

stage form. This will be needed for the upcoming
charts.

As we have some new functionality in the DeploymentPlatform query, we
should validate this on staging at least before enabling to everyone.

Fixed a bug uncovered where we need to refer to top-level `::Project`
constant.

When working out the deployment platform for a project, only return
clusters where its namespace is the same as the management project.

This ensures that cluster credentials won't leak out of the namespace.

Allow where managment project is in the hierarchy of the cluster's
namespace as well.

- For group clusters, this is achieved by simply changing the order
clause
- For project clusters, we need to have a new query in our CTE to fetch
clusters where management cluster is in the same namespace as the
project's namespace.

Add specs for new code, alter existing specs to work with new
restrictions.

And finally update documentation!

Only allow cluster to update management_project to namespace (and
descendants) of the cluster.

For instance-level cluster, this is meaningless so skip for this cluster
type.

Also returns management_project details on POST and PUT

For project and group cluster

Adds service to update the management_project_id for a cluster.

The management_project_id referred to must be be authorized for the
current user.
