Add foundational components and logic for migration, UI design, and input handling

- Introduced foundational UI components (`Badge`, `LockCard`, `SectionHeader`, `AvatarIcon`, etc.) for flexible layouts and consistent design.
- Added migration support with the `MigrationModal` component and backend integration for exporting/importing data between Electron and Tauri.
- Extended form components with `TextAreaInput`, `OrderInput`, `ToggleField`, and `ToolbarSelect` for improved input handling.
- Updated `ScribeShell` with migration popup logic to prompt users for data migration.
- Integrated `AlertStack` for better alert handling and notification management.
- Enhanced Rust/Tauri services with migration command implementations.
- Added translations and styles for new components.
