feat: [lungmap] add lungmap projects to google datasets catalog (#4808)

[frano-m]

Summary

Adds Schema.org Dataset JSON-LD to LungMAP project detail pages so Google Dataset Search can index them. Completes the three-consumer rollout alongside #4806 (HCA) and #4807 (AnVIL).

LungMAP shares the HCA Azul backend, so this PR refactors the HCA builder into a shared parameterized core (buildProjectJsonLd) and adds a thin LungMAP wrapper supplying its own catalog identity.

Refactor:

• NEW app/utils/schemaOrg/projectDataset.ts — shared buildProjectJsonLd(data, browserURL, options) core extracted from hcaProjectDataset.ts (lift-and-rename; logic unchanged). Defines ProjectCatalogOptions for catalog identity (catalogName, descriptionFallbackSuffix).
• app/utils/schemaOrg/hcaProjectDataset.ts — reduced to a 27-line wrapper passing HCA catalog config.

LungMAP:

• NEW app/utils/schemaOrg/lungmapProjectDataset.ts — 27-line wrapper passing LungMAP catalog config.
• NEW __tests__/utils/schemaOrg/lungmapProjectDataset.test.ts — 3 tests verifying LungMAP catalog identity + URL pattern + description padding (the shared core is covered by the 14 existing HCA tests).
• pages/[entityListType]/[...params].tsx — added isLungMap = siteConfig.appTitle?.includes("LungMAP") guard and mount via the generic renderJsonLd helper introduced in [AnVIL DX] Add AnVIL datasets to Google Datasets catalog #4807.

Closes #4808. Stacked on #4831 (AnVIL PR), which is stacked on #4829 (HCA PR). Once #4829 and #4831 merge, rebase this PR's base to main.

LungMAP-specific differences from HCA: catalogName = "LungMAP Data Explorer", padding suffix "LungMAP Data Explorer project.". Every other mapping is identical because LungMAP uses HCA's ProjectResponse shape.

Test plan

• npx tsc --noEmit passes
• npm run lint, npm run check-format pass
• npx jest __tests__/utils/schemaOrg — 28/28 tests pass (14 HCA + 11 AnVIL + 3 LungMAP)
• npm run build-dev:lungmap — 4/10 project detail pages emit JSON-LD with "name":"LungMAP Data Explorer" catalog (remainder are sub-tab routes where processEntityProps short-circuits — same gating pattern as HCA/AnVIL)
• npm run build-ma-dev:hca-dcp — HCA still 110/116 (no regression from the core extraction)
• npm run build:anvil-cmg — AnVIL still 375/422 (no regression)
• npm run build-dev:anvil-catalog — clean, no JSON-LD (correctly gated)
• Validate output against Google's Rich Results Test and Schema Markup Validator after deploy
• Request indexing via Google Search Console post-merge
