rustdesk-server/src/api/groups.rs

//! `GET /api/device-group/accessible` — paginated list of device groups the
//! caller is a member of (admin sees all). The Flutter client at
//! flutter/lib/models/group_model.dart:103 silently tolerates errors here, so
//! we keep the behavior tight: empty list when no groups exist, never panic.
