Previously, the API endpoint only invoked setup hooks during initial container creation or cloning. Introduce a new `post_restore_hook` in the LXC setup plugin architecture. This hook applies the provided credentials if they are defined. Move `template_fixup` to the `post_restore_hook`, matching the creation logic.
