fix: keep Windows notification badge state in sync

[huhuanming]

Summary

• Replace electron-taskbar-badge with a OneKey-owned Windows taskbar badge helper.
• Keep badge state synchronized across clear, window show, accent-color changes, and overlapping asynchronous renders.
• Remove the third-party dependency and its patch-package patch.

Intent & Context

This is a follow-up to #12447. The CommonJS loader fixed the original BadgeGenerator2 is not a constructor crash, but clearing the Windows notification badge could still restore the previous count.

The stale badge was reproduced after hiding/showing the window, changing the Windows accent color, and resolving an older asynchronous badge draw after a clear.

Root Cause

The previous clear path updated BrowserWindow.setOverlayIcon() without synchronizing the third-party package's module-level state. The package also allowed an older executeJavaScript() render to overwrite a newer clear.

Design Decisions

• Reimplement only the required behavior in OneKey source instead of carrying a source patch for the GPL-licensed dependency.
• Generate a PNG data URL with a controlled renderer canvas because Electron NativeImage supports PNG/JPEG data.
• Use Electron's Windows accent-color API and refresh the icon when that color changes.
• Keep the count, current image, and update version in one class so clears invalidate pending renders.
• Remove listeners when the BrowserWindow closes.

Changes Detail

• packages/kit-bg/src/desktopApis/WindowsTaskbarBadge.ts: OneKey-owned badge rendering and lifecycle implementation.
• packages/kit-bg/src/desktopApis/WindowsTaskbarBadge.test.ts: regression coverage for clear/show/accent behavior and stale renders.
• packages/kit-bg/src/desktopApis/DesktopApiNotification.ts: use the local helper for Windows badge updates.
• package.json / yarn.lock: remove electron-taskbar-badge.
• patches/electron-taskbar-badge+1.1.2.patch: remove the obsolete dependency patch.

Risk Assessment

• Risk Level: Medium
• Affected Platforms: Desktop (Windows)
• Risk Areas: Windows taskbar overlay rendering and BrowserWindow lifecycle timing.

Test plan

• Type-aware oxlint on all changed TypeScript files.
• Jest regression: clear remains after window show and accent-color changes.
• Jest regression: stale async render cannot overwrite clear.
• Electron main-process development build.
• Bundle inspection confirms no electron-taskbar-badge code remains and the stale-render guard is present.

当窗口已有旧 badge，而新的非零更新在 executeJavaScript、data URL 校验或 nativeImage 校验任一阶段失败时，这里已经把 currentCount 更新为新值，但 currentOverlayIcon 和任务栏仍保留旧图片。之后触发 show 会再次挂载旧数字，并使用新计数 description，导致可见 badge 与内部状态长期不一致。

请把 count 与 overlay icon 作为一次原子提交：仅在最新版本成功生成图片后同时写入；若最新版本渲染失败，则明确清空 overlay 状态，不能继续保留旧图标。
