fix: expose NodeStatus as KBucketNodeStatus

The EntryView struct exposes the node status however its type is not public making it impossible to
use the status field.

This change re-exports NodeStatus according to the existing naming pattern.
See #4108 which was fixed however the NodeStatus type
was not exposed.
