mgr/dashboard: Let the user know if it's safe to destroy/delete/remove an OSD
The user is going to be warned if the selected OSD cannot safely be destroyed/deleted/removed, but there's not visual indication if the desired operation is safe.
For the warning, warning panel is used. It makes sense to use a success panel for positive outcomes.
ceph osd safe-to-destroy now also supports JSON output: https://github.com/ceph/ceph/pull/24799
