Only ROLE_ADMIN can perform data storage mounts

[sidoruka]

Problem

The mount_restrictor script only allows users with ROLE_ADMIN to perform data storage mount operations. Users who have ROLE_STORAGE_ADMIN (storage administration rights) but not full admin are blocked from mounting, even though their role is intended to manage storage.

Impact

• Storage admins cannot use mount functionality (e.g. mount data storages in runs or environments) without being granted ROLE_ADMIN.
• Behavior is inconsistent with the purpose of ROLE_STORAGE_ADMIN.

Expected behavior

Users with ROLE_STORAGE_ADMIN should be able to perform data storage mounts in the same way as users with ROLE_ADMIN, without requiring full admin rights.
