perf(ci): run unit-tests in parallel with build in frontend-pr-workflow

[kb-typeform]

Summary

• Removes needs: build from the unit-tests job in frontend-pr-workflow.yml.
• unit-tests does not consume the build artifact (no Download Build Artifacts step, no needs.build.outputs.* reference) and already re-runs any required codegen in pre-test-command. The dependency only serialized the pipeline for no functional gain.
• After this change, unit-tests runs in parallel with build, shortening PR feedback time.

Scope

Investigated all 32 frontend repos migrated to the unified CI pipeline (PLT-2547):

• 18 repos actively benefit — jest-only test suites or pre-test-command: yarn generate that is self-contained (smart-forms-builder, audiences-page, admin-panel, followups-manager, typeform-ai, authbridge-fe, auth-page, boombox-fe, cha-ching, hall-of-forms, paprikations, typekit-app-directory, share-web, workflows, results, integrations-panel, chief, demo-app).
• 10 repos unaffected — don't call this workflow, or don't run unit tests via it.
• 4 repos with workspace-aware pre-test — admin-template-gallery, brand-kit-frontend, app-shell, performance-analytics. All handle their test prereqs via pre-test-command independently of the build job, so removing the dep is safe.

Validation

End-to-end test against performance-analytics (the repo with the most complex pre-test — Turbo workspace rebuilds + GraphQL codegen):

• Pointed Typeform/performance-analytics#2008 at @test/unit-tests-no-build-dep.
• Unit Tests started 14:17:08; Build started 14:17:18 — parallel execution confirmed.
• Unit Tests completed in 6m44s (while Build took 3m48s).
• No Turbo cache contention or codegen ordering issues observed.

Time savings on this PR: ~3m48s on the unit-tests critical path (equal to the full build duration, because unit-tests > build here). For repos where unit-tests < build, savings equal the unit-tests duration on any path that gates on unit-tests completion (e.g. SonarCloud, which currently needs: [build, unit-tests]).

Flakes observed during validation were pre-existing (intermittent GraphQL schema fetches, Playwright timeouts) and reproduce on unmodified PRs.

Test plan

• Validated against performance-analytics with end-to-end rerun
• Confirmed Unit Tests starts before Build in parallel mode
• Monitor next-day CI for regression reports across affected repos

---

• This PR only changes an existing workflow.
• This PR adds a new workflow that is needed in a public Typeform repository.
