fix: improve test isolation for managed event type e2e tests (#26283)

- Move managedEventTypeSlug generation inside beforeAll to ensure uniqueness across test runs
- Add deleteAllTeamEventTypes method to EventTypesRepositoryFixture
- Explicitly delete all team event types in afterAll before deleting teams

This fixes flaky tests in organizations-member-team-admin-event-types.e2e-spec.ts
where the managed event type creation was intermittently failing with 400 Bad Request.
