[dashboard-language] Built-in pages: verify dashboard.json coverage gates

Summary

• re-ran the full pages/dashboard/ quality gates after the authoritative dashboard.json built-in coverage slice
• fixed strict checkJs typing for the built-in renderer registry and authoritative dashboard structure assertions without changing runtime behavior
• updated pages/dashboard/PLAN.md to record the verified gate rerun and mark the built-in coverage proof subtask complete

Milestone

• Built-in pages

Specification coverage

• DLS-PAGE-001 through DLS-PAGE-014 via authoritative dashboard.json inventory coverage already exercised by the presenter and reaffirmed by this gate rerun
• quality-gate proof for the Built-in pages plan subtask: build/unit/browser coverage for all 12 specification-defined built-in pages under the current renderer architecture

Gates

• npm install ✅
• npm run typecheck ✅
• npm run lint ✅
• npm test ✅
• npx playwright test --config=playwright.config.mjs ✅

Blockers

• None in this run

Next milestone

• Built-in pages: continue refactoring remaining built-in page body composition out of src/presenter.js and into generic interpretation of declarative dashboard.json definitions
