test: raise unit test coverage to 75.7% and stabilize test environment

[pengfeixx]

Add unit tests for UI/DeviceManager/DBus/HTTP modules to raise line coverage.

为 UI/DeviceManager/DBus/HTTP 等模块新增单元测试，提升行覆盖率。

Fix cmake 3.31 Qt version misdetection and stub DBus calls in test_main.

修复 cmake 3.31 下 Qt 版本误检，并在 test_main 全局桩 DBus 调用避免服务阻塞。

Log: 提升单元测试覆盖率至75.7%并稳定测试环境
Influence: 前端覆盖率70.3%→75.7%，1100测试通过；修复cmake Qt6误检与DBus测试阻塞。

★ 总体评分：95分

■ 【总体评价】

代码实现了CMake Qt版本探测修复并大幅补充了单元测试，质量良好但存在轻微内存泄漏
逻辑正确且测试覆盖全面，因全局桩对象未释放扣5分

■ 【详细分析】

• 1.语法逻辑（完全正确）✓

CMakeLists.txt中将find_package拆分为显式探测Qt6再fallback Qt5的逻辑严谨，准确规避了CMake 3.31+的NAMES误检问题。新增的约20个测试文件准确覆盖了DeviceInput::getDetailBusInfo等核心函数的各个分支，Stub桩函数的签名与原函数严格匹配，测试断言使用合理。
建议：无

• 2.代码质量（良好）✓

测试代码注释详尽，清晰说明了跳过某些用例的原因（如QProcess阻塞、Docx构造SEGV等）。使用-fno-access-control和Stub桩隔离了QProcess、QDBusInterface等外部依赖，测试解耦性好。
潜在问题：test_main.cpp中通过new创建的Stub对象未在进程结束前释放，造成内存泄漏；ut_devicemanager_save.cpp中硬编码了/tmp/ut_dm_out.txt等固定路径，在并行测试时可能产生文件读写冲突。
建议：将test_main.cpp中的Stub对象改为栈分配以自动析构释放；在ut_devicemanager_save.cpp中使用QTemporaryDir动态生成不冲突的临时文件路径。

• 3.代码性能（无性能问题）✓

测试代码仅在编译和运行测试阶段生效，对生产环境的运行时性能无任何影响。CMake的探测逻辑改动仅在配置阶段执行一次，开销可忽略。
建议：无

• 4.代码安全（存在0个安全漏洞）✓

漏洞对比统计：新增漏洞 0 个，减少漏洞 0 个，持平 0 个
代码变更全部位于构建脚本和测试模块中，不涉及生产环境的业务逻辑、网络通信或权限提升，不存在命令注入、路径遍历等安全风险。测试中硬编码的/tmp路径在Linux环境下属于安全可写目录，不构成安全漏洞。
建议：无
