fix(theme): skip initGlobalTheme for treeland environment

[mhduiy]

Treeland does not need global theme initialization logic. All personalization settings in treeland follow the control center protocol instead.

treeland环境下跳过全局主题初始化，treeland下所有个性化设置走控制中心协议。

Log: treeland下跳过全局主题初始化
PMS: TASK-391987
Influence: treeland环境下不再执行全局主题初始化，避免与控制中心协议冲突。

Reviewer's Guide

This PR updates the global theme initialization logic so that in the Treeland environment global theme init is skipped and the theme is instead aligned with the property-based value, avoiding conflict with the control center protocol.

**suggestion:** Evaluate whether qInfo is the appropriate log level for this path, given it runs on every Treeland startup.

Since this runs on every Treeland startup, please confirm whether this message is truly noteworthy in production. If it’s part of a normal path, consider downgrading to debug or removing it to reduce log noise; otherwise keeping it at info is fine.

```suggestion
    // treeland 不需要走初始化全局主题逻辑，treeland下所有的个性化设置全部走控制中心的协议
    if (utils::isTreeland()) {
        // 正常启动路径上的日志，降低到 debug 级别以减少生产环境中的日志噪音
        qDebug() << "treeland, skip initGlobalTheme";
        m_currentGlobalTheme = m_property->globalTheme;
        return;
    }
```

★ 总体评分：100分

■ 【总体评价】

代码增加了对treeland环境的跳过逻辑，质量优秀且无任何安全风险
逻辑正确、注释清晰、性能无损耗且无安全漏洞，满分通过

■ 【详细分析】

• 1.语法逻辑（完全正确）✓
  在 AppearanceManager::initGlobalTheme() 函数入口处增加了条件判断，使用 if 语句结合提前返回控制流程，未发现语法或逻辑错误。
  建议：保持现有逻辑。

• 2.代码质量（优秀）✓
  注释准确说明了跳过初始化全局主题逻辑的业务原因，代码简洁明了，变量使用符合上下文规范。
  建议：保持现有注释风格。

• 3.代码性能（高效）✓
  在 treeland 环境下通过提前返回避免了后续 listGlobalThemes 等潜在的资源消耗操作，非 treeland 环境仅增加一次极低开销的条件判断。
  建议：无需优化。

• 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
  代码仅包含环境检测与变量赋值，未引入外部输入处理、内存操作或命令执行，无安全风险。
• 建议：继续保持安全的编码习惯。

■ 【改进建议代码示例】

// 当前代码已足够优秀，无需改进，此处展示当前最佳实践
void AppearanceManager::initGlobalTheme()
{
    // treeland 不需要走初始化全局主题逻辑，treeland下所有的个性化设置全部走控制中心的协议
    if (utils::isTreeland()) {
        qInfo() << "treeland, skip initGlobalTheme";
        m_currentGlobalTheme = m_property->globalTheme;
        return;
    }

    QVector<QSharedPointer<Theme>> globalList = m_subthemes->listGlobalThemes();
    bool bFound = false;
}
