From dde4683c3845f7ecba78786c032f625b228a4763 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Migrate from `electron-store` to OS-level secure storage
 (`getSecureStorage`)

- Replace `electron-store` with OS-level encrypted storage for secure token, userId, and language management in `LocalSystem` and `keyManager`.
- Add `init-user` IPC handler to initialize user data and manage encryption keys.
- Update login process to handle encrypted storage saving with fallback for macOS issues.
- Add offline warning component to `login/page.tsx` to handle first-time sync requirements.
- Remove `electron-store` and associated dependencies from `package.json` and `package-lock.json`.
