test(e2e): run composed profile suites against the bundled UI app

[alexcarpenter]

Description

Fixes flaky @generic runs caused by the composed profile suites. Each suite built and booted its own Next.js app in beforeAll with an extra @clerk/ui install (21–27s on CI), then waited on the first next dev compile, which regularly exceeded the 30s hook timeout. When that happened the dev server was never killed, loading the shared runner and slowing unrelated suites.

• The composed tests (integration/tests/composed/) now run against the existing next.appRouterBundledUI long-running app, which already depends on @clerk/ui. The composed pages live in the next-app-router-bundled-ui template, so the suites no longer boot an app or need custom hook timeouts.
• Adds a composed CI job (test:integration:composed, @composed tag) that runs these suites against the bundled UI app, in both the PR and staging e2e matrices (they previously ran inside generic, which is in both). The template's themes page is updated from the removed baseTheme appearance prop to theme so the app builds.
• integration/models/application.ts: dev() and serve() register the process kill right after spawning instead of after the server responds, so a beforeAll timeout during startup no longer leaves a dev server running (previously causing ENOTEMPTY on teardown).

📝 Walkthrough

Walkthrough

The dev and serve paths now register process cleanup before waiting. The bundled UI template adds composed user and organization profile routes and updates its sign-in theme examples. Playwright suites cover composed profile and security flows, replacing the previous composed-components test file. The package script, Turbo task, and CI matrices add composed integration-test support.

Merge Risk: ⚪ Minimal · up to 40bba

The composed staging leg is wired to tasks present at the reviewed head. Compatibility with older release refs remains unverified, but no concrete merge-blocking failure is established.
