fix(managed-ne): prevent ume-sync route conflicts and prefer host_name

Ensure fixed managed-ne paths are matched before /{ne_id} so deleting UME-synced NEs no longer triggers managed_ne_not_found, and use UME host_name as the synced display name to align managed NE naming with inventory host identity.
