* fix: make team migrations sequential to avoid race conditions Instead of processing team migrations in parallel using Promise.all, process them sequentially to avoid race conditions when creating profiles and memberships for team members. This simplifies the implementation and avoids the need for complex retry logic or database-level concurrency controls. * Promise.all accepts an array of promises and not an array with array in it as the first item. This fixes the issue where these promises were unhandled * Fix the issue where an existing pending membership with team stays pending even though theorganization membership gets created as accepted
