* feat: migrate DefaultUserCollection to SharedCollection during user deletion
- Implemented migration of DefaultUserCollection to SharedCollection in EF UserRepository before deleting organization users.
- Updated stored procedures User_DeleteById and User_DeleteByIds to include migration logic.
- Added new migration script for updating stored procedures.
* Add unit test for user deletion and DefaultUserCollection migration
- Implemented a new test to verify the migration of DefaultUserCollection to SharedCollection during user deletion in UserRepository.
- The test ensures that the user is deleted and the associated collection is updated correctly.
* Refactor user deletion process in UserRepository
- Moved migrating DefaultUserCollection to SharedCollection to happen before the deletion of user-related entities.
- Updated the deletion logic to use ExecuteDeleteAsync for improved performance and clarity.
- Ensured that all related entities are removed in a single transaction to maintain data integrity.
* Add unit test for DeleteManyAsync in UserRepository
- Implemented a new test to verify the deletion of multiple users and the migration of their DefaultUserCollections to SharedCollections.
- Ensured that both users are deleted and their associated collections are updated correctly in a single transaction.
* Refactor UserRepositoryTests to use test user creation methods and streamline collection creation
* Ensure changes are saved after deleting users in bulk
* Refactor UserRepository to simplify migration queries and remove unnecessary loops for better performance
* Refactor UserRepository to encapsulate DefaultUserCollection migration logic in a separate method
* Refactor UserRepository to optimize deletion queries by using joins instead of subqueries for improved performance
* Refactor UserRepositoryTest DeleteManyAsync_Works to ensure GroupUser and CollectionUser deletion
