Subject: [PATCH] refactor(auth): remove database trigger and update user
 creation

Removed the database trigger for setting `canImpersonate` for the first user and implemented the logic directly in the `sign-in-up.service`. This simplifies the code by handling the first user creation within the application layer, ensuring better maintainability.
