Enhance user management with SUPER_ADMIN access control

- Updated the user list retrieval logic to ensure proper filtering based on company codes, enhancing security for user data access.
- Implemented checks to restrict access to company management APIs, allowing only SUPER_ADMIN users to perform actions related to company data.
- Adjusted the user interface to reflect access restrictions for non-SUPER_ADMIN users, providing clear feedback when access is denied.

These changes strengthen the integrity of user management and ensure that sensitive company information is only accessible to authorized personnel.
