fix: 主题模板真正应用到主面板渲染

根本问题: buildPanelView('main') 构建主面板时用的是
ui.colors.bgLight/bgDark（Monet 配色），完全不经过
getPanelBgColorInt/getPanelTextColorInt 的模板填充逻辑。
updatePanelBackground 虽然封装了统一取色，但实际没有在
主面板构建流程中被调用。

修复:
1. buildPanelView('main') 末尾调用 updatePanelBackground(panel)
   应用统一主题色（Monet/模板/自定义）
2. 保留临时背景色避免构建过程中的裸窗口闪烁
