feat(admin-ui): make Tutorials OP facets readable (concepts/community/images)

[jung-thomas]

What & why

Three facets on the Tutorials Object Page in the admin UI showed raw keys or blanks. Tom's feedback:

Images — Bytes is empty… a link to the object in the object store? … and a link to the output of the image from the tutorial system itself? Concepts Taught — it only shows a GUID of the Concept ID… we really need a description. Similar on Community — it shows a numeric ID but no description.

Changes

• Concepts Taught — annotate the concept association with @Common.Text: concept.name (#TextOnly) so the FK renders the concept name instead of a GUID.
• Community — expose KgCommunityLabelInfo (projection on the existing KgCommunityLabel) + a labelInfo select-list association joined on communityFingerprint; annotate communityId with @Common.Text: labelInfo.label (#TextFirst). LineItem now shows Community (labelled) + member slug + type (fingerprint dropped). Label is blank until the Louvain labeling job ([Leverage KG communities in learner-facing surfaces and Joule #1126]) runs in an env — the member slug is the always-present fallback.
• Images — add virtual thumbUrl/viewUrl to the TutorialImages projection, filled in after('READ') from sourceUrl:
  • thumbUrl → approuter /img-cdn (resize/WebP preview), rendered inline via @UI.IsImageURL
  • viewUrl → CAP /content/image-source (raw original, self-heals from object store)
  • LineItem leads with the inline thumbnail + an "Image (served)" link alongside the existing Source (GitHub) link and the Type / Bytes / Hash / Channel store details.
  • Note: empty Bytes on some rows is legacy data (rows ingested before byteSize existed); fresh ingest populates it.

Tests

test/unit/admin-facet-readability.test.js — CSN annotation guards for all three + a served runtime check of the image URL enrichment (incl. null-sourceUrl skip). EDMX verified: annotations land on concept_ID, communityId, thumbUrl. Full compile clean; related admin/community suites green.

Deploy note

Admin-UI change — requires a FULL deploy (npm run deploy -- --env <env>, no --skip-build / no -m scoping) to view; the admin bundle is raw-copied into the approuter at mbt build.

No srv/lib change (no srv-qa cp-list impact); KgCommunityLabelInfo is a projection on an already-persisted entity (no migration).
