fix: 修复通过 dde-dconfig-editor 修改字体后控制中心 UI 不刷新

[mhduiy]

问题

PMS BUG-353505

用户通过 dde-dconfig-editor 手动修改 org.deepin.dde.appearance 的标准字体或等宽字体后，控制中心 UI 不刷新，仍显示旧字体。

根因

handleSettingDConfigChange 中 GSKEYFONTSTANDARD / GSKEYFONTMONOSPACE 两个分支只调用了 doSetStandardFont / doSetMonospaceFont 应用字体变更，但遗漏了 setStandardFont / setMonospaceFont 来更新 DBus 属性 m_property。

m_property 未更新 → PropertiesChanged DBus 信号未发出 → 控制中心 Q_PROPERTY NOTIFY 信号未收到 → UI 不刷新。

证据

• doSetStandardFont / doSetMonospaceFont 内部不调用 setXxx（与 doSetGtkTheme / doSetIconTheme / doSetCursorTheme 内部已调用 setXxx 不同），形成确定性遗漏。
• 同文件 Set 方法对 TYPESTANDARDFONT / TYPEMONOSPACEFONT 使用 doSetXxx + setXxx 正确写法。
• handleSettingDConfigChange 中 GSKEYGLOBALTHEME 分支也使用 doSetGlobalTheme + setGlobalTheme 正确写法（doSetGlobalTheme 内部同样不调用 setGlobalTheme）。

修复

在 handleSettingDConfigChange 中为两个分支补充 setXxx 调用，与 GSKEYGLOBALTHEME 分支保持一致：

bSuccess = doSetStandardFont(value);
if (bSuccess) {
    setStandardFont(value);      // 新增
}
// monospaceFont 同理
bSuccess = doSetMonospaceFont(value);
if (bSuccess) {
    setMonospaceFont(value);     // 新增
}

改动量：6 行，仅涉及 appearancemanager.cpp。setStandardFont / setMonospaceFont 内部有值比对守卫，无重复触发风险。

影响

仅 standardFont / monospaceFont 两个设置项受影响，其余设置项不受影响。
