ci(frontend): publish SPA coverage by module on PRs

[mariusmm]

Summary

• Run Vitest coverage (npm run test:coverage) in the frontend-tests CI job
• Roll up line/branch/function rates by frontend/src module via scripts/frontend-coverage-summary.mjs
• Publish the markdown summary to the GitHub Actions job summary and as a dedicated PR comment (message-id: frontend-coverage)
• Upload HTML/LCOV/Cobertura artifacts; keep legacy marreq-core/tests/js tests as a separate step

Coverage snapshot (local, current suite)

5.7% lines (768 / 13,489) across the SPA — existing 74 tests.

Module	Line rate
lib	82.5%
utils	79.2%
context	39.7%
hooks	18.1%
components/graph	16.3%
components	5.8%
pages	5.2%
api	2.9%
pages/catalog / pages/groups	0%

No coverage gate was added for frontend (would fail at ~6%). Backend gate remains 70%.

Test plan

• CI frontend-tests is green
• PR shows a Frontend SPA coverage comment with module table
• Job summary includes the same table
• Artifact frontend-coverage-html is uploaded
• Legacy JS tests still run
