fix: resolve flaky team-management E2E test (#28575)

* fix: resolve flaky team-management E2E test

Fix two failure modes in the 'Can create teams via Wizard' test:

1. Strict mode violation: locator('[data-testid=new-team-btn]') resolves to
   2 elements during Next.js streaming/hydration. Fixed by using .first().

2. Race condition in disband assertion: raw .count() check doesn't wait for
   UI to update after team deletion. Replaced with Playwright's auto-retrying
   toBeHidden() assertion with a 10s timeout.
