GHSA-48x2-6pr9-2jjf: Network-AI: EnvironmentManager.restore() backup ID path traversal copies arbitrary directories into environment data

The `EnvironmentManager.restore()` function in Network-AI 5.12.1 is vulnerable to path traversal (a technique where an attacker uses sequences like `../` to access files outside the intended directory). An attacker can pass a malicious backup ID to copy arbitrary files from anywhere on the system into the environment's data folder, potentially exposing sensitive information or breaking environment isolation.
