E2E: remove dead code

[phyllis-sy-wu]

WHY are these changes introduced?

These scripts are unused — nothing imports or calls them. They've been replaced by cleanup-apps.ts and the test fixtures that create apps directly.

WHAT is this pull request doing?

Removes two dead scripts from packages/e2e/scripts/:

• cleanup-test-apps.ts — original cleanup script, superseded by cleanup-apps.ts (E2E: utility - cleanup apps #7356)
• create-test-apps.ts — standalone app creation utility, superseded by test fixtures (appTestFixture in setup/app.ts)

Neither file is imported, referenced in package.json, or called from any other file in the repo.

How to test your changes?

grep -r "cleanup-test-apps\|create-test-apps" packages/e2e/ --include="*.ts" --include="*.json"
# Should return nothing
