Add OAuth login support and streamline authentication flows

- Introduced `oauthLogin` method in `electron/preload.ts` and backend IPC handlers for OAuth via `BrowserWindow`.
- Replaced web-based OAuth redirection with Electron-specific implementation for Google, Facebook, and Apple.
- Refactored `SocialForm.tsx` to handle OAuth login success and token management via Electron.
- Updated `User`, `QuillSense`, and context methods to include `quill-trial` subscriptions and extended login logic.
- Cleaned up code, removed unused imports, and improved error handling for authentication scenarios.
