[dashboard-components] Extract shared report list renderer

[github-actions]

Summary

• extract pages/dashboard/src/components/report-list.js to share durable-report rendering between package and workflow detail views
• replace the duplicated report filtering, summary counting, row rendering, and empty-state handling in pages/dashboard/src/components/package-detail.js and pages/dashboard/src/components/workflow-detail.js
• add focused unit coverage in pages/dashboard/test/unit/report-list.test.js and update pages/dashboard/PLAN.md

Duplication evidence

• pages/dashboard/src/components/package-detail.js previously owned package-report filtering, summary counting, card-row rendering, and empty/no-match states.
• pages/dashboard/src/components/workflow-detail.js previously owned the same durable-report concerns in a table-shaped variant.
• Both call sites now compose the shared renderer with container-specific wrappers only.

Call sites collapsed

• pages/dashboard/src/components/package-detail.js → package reports
• pages/dashboard/src/components/workflow-detail.js → workflow reports

Tests added

• pages/dashboard/test/unit/report-list.test.js
  • package-card rendering and summary counts
  • workflow-table rendering
  • filter no-match behavior
  • empty/unavailable fallback coverage
  • external-link fallback when no safe-output id exists

Quality gates

• npm install ✅
• npm run typecheck ✅
• npm run lint ✅
• npm test ✅
• node ./scripts/build.mjs ✅

Behavior preservation proof

• Existing assertions in pages/dashboard/test/unit/package-detail.test.js and pages/dashboard/test/unit/workflow-detail.test.js remained in place and passed unchanged after both views switched to the shared renderer.
• The affected package-report card view still preserves hidden-row filtering behavior, DOM text, class names, links, and badge semantics.
• The affected workflow-report table view still preserves DOM text, class names, links, summary counts, and empty messages.

Blockers

• Browser snapshot comparison was not completed in-session because Playwright browser tools were not exposed here; this run relied on the existing affected-page unit assertions for rendered-output preservation.

Next candidates

• shared tablist controller across pages/dashboard/src/components/packages-view.js and pages/dashboard/src/components/package-detail.js
• shared report/repository navigation tabs across pages/dashboard/src/components/package-detail.js, pages/dashboard/src/components/workflow-detail.js, and pages/dashboard/src/components/repository-workflows.js
• shared static table-section wrapper across pages/dashboard/src/components/packages-view.js, pages/dashboard/src/components/repository-workflows.js, and pages/dashboard/src/components/ui-elements.js
