"""
The `TeamUser` class is a custom user model that extends the `AbstractBaseUser` and `PermissionsMixin` classes from Django's built-in authentication system. It provides a user model with the following fields:
- `email`: The user's email address, which is used as the unique identifier for the user.
- `first_name`: The user's first name (optional).
- `last_name`: The user's last name (optional).
- `dapsy`: A boolean field indicating whether the user is a DAPSY user.
- `is_active`: A boolean field indicating whether the user is active.
- `is_admin`: A boolean field indicating whether the user is an admin.
- `team`: A foreign key relationship to the `Team` model, indicating the team the user belongs to.
- `lead_for`: A many-to-many relationship to the `engagements.Organisation` model, indicating the organizations the user is a lead inspector for.
- `designation`: The user's designation (optional).
The `TeamUser` class also overrides the default user manager with the `TeamMgr` class, which provides custom methods for creating regular and superuser accounts.
The `__str__` method returns the user's email address, and the `fullname` method returns the user's full name (first and last name).
The `has_perm` and `has_module_perms` methods are placeholders that always return `True`, indicating that the user has all permissions. The `is_staff` property is also a placeholder that returns the value of `is_admin`.
