[backport cloud/1.41] feat: improve essentials tab blueprint support and display names (#10161)

Backport of #10113 to `cloud/1.41`

Cherry-picked merge commit d6c1dd2e59.
Resolved import conflict in `NodeLibrarySidebarTabV2.vue` — kept
cloud/1.41's `SearchBox` component import, added new
`resolveBlueprintSuffix` import from the PR.
