Unregister plugin event bus on unload; expose registerCustomEventBus on window.siyuan

[TCOTC]

Description / 描述

• 插件关闭时自动取消注册事件总线 插件关闭时自动移除所有事件监听器 #16910
• 暴露一个 registerCustomEventBus() 函数到 window.siyuan，供 JS 代码片段或者主题使用事件总线（直接用内部事件总线的性能应该要比写一堆监听器更好）
• 封装了 emitToEventBus 函数，修改了几乎所有 emit 处的代码，同时删除了一部分不再需要使用的参数。比如 lockScreen() 函数去掉了 app 参数，另外还需要修改 petal

Pull request overview

This PR enhances the plugin event bus lifecycle and makes the event bus available to non-plugin code (JS snippets/themes) by exposing registerCustomEventBus() on window.siyuan, while also refactoring many internal event emissions to go through a shared emitToEventBus() helper.

Changes:

• Add EventBus.destroy() and invoke it on plugin uninstall to auto-unregister event listeners on unload.
• Expose registerCustomEventBus() on window.siyuan (and type it) so snippets/themes can register their own event buses.
• Refactor many plugin.eventBus.emit(...) loops to a centralized emitToEventBus(...) helper and simplify some call signatures (e.g., lockScreen, processSync, flashcard emit helper).
