fix(desktop): release Electron storage locks before wiping user data on Windows

[Copilot]

On Windows, "Wipe data" from Debug settings fails with EBUSY: resource busy or locked because Electron's Chromium storage service holds open file handles on DIPS and DIPS-val SQLite databases in the user data directory while the app is running.

Description

• packages/suite-desktop-core/src/libs/user-data.ts: In clear(), call session.defaultSession.clearStorageData() before fs.promises.rm(). This closes all storage handles held by the Chromium storage service (IndexedDB, cookies, DIPS, etc.), releasing the Windows file locks so the directory can be deleted.

+import { app, session, shell } from 'electron';

 export const clear = async (): Promise<InvokeResult> => {
     const dir = path.normalize(app.getPath('userData'));
     try {
+        // Clear session storage to release file locks before deleting user data directory.
+        // On Windows, Electron keeps DIPS and DIPS-val files locked by the storage service.
+        await session.defaultSession.clearStorageData();
         await fs.promises.rm(dir, { recursive: true, force: true });

Notes for QA

On Windows: Settings → Debug → Wipe data → should complete without EBUSY error and app should restart cleanly with no user data.
