This is the same as the previous commit, but when a namespace changes
its parent namespace via a transfer. (The previous commit is for a
namespace changing its own path directly.) We're moving Pages disk
operations from Puma to Sidekiq, and here that's behind the
`async_pages_move_namespace_transfer` feature flag.

When we rename a namespace, any projects in that namespace with Pages
enabled have to have their directories moved on the filesystem to match.
We want all operations that touch Pages disk paths to happen in Sidekiq,
not Puma; this puts that in Sidekiq behind the
`async_pages_move_namespace_rename` feature flag.

Use active user count instead of historical max

Closes #224681

See merge request gitlab-org/gitlab!37916

"User count threshold" banner should use
active user count instead of historical max
to reflect the current state.

The worker specs should just test the worker's behaviour, which is
calling the service. The service specs should test the operations on
disk.

When we rename a project, we call Gitlab::PagesTransfer to move any
pages directory on disk. This makes it convenient to use that class
through Sidekiq instead, so that Puma no longer needs access to Pages
NFS mounts.
