clustri/src-tauri/tests/api_client.rs

//! Integration tests for the Proxmox API client core.
//!
//! These tests exercise the generic `api_request` helper against a local HTTP
//! mock server, covering auth header injection, response envelope unwrapping,
//! error mapping, query parameters, and URL construction.
