This commit removes the FlowStyles table from the database. The table was no longer needed and has been dropped. The corresponding indexes and foreign key constraints have also been removed.
Downgrade functionality has been implemented to recreate the FlowStyles table and its associated indexes and foreign key constraints if needed.
The LoginPage component is added to handle the user login functionality. It includes UI elements such as buttons, icons, and input fields for email address and password. The component also includes a login button and a sign-up button for users who don't have an account.

🔧 chore(utils.py): refactor code to improve readability and remove unused imports
- Added `__init__.py` file to the `services` directory to make it a package.
- Created `Service` class in `base.py` to serve as a base class for different services.
- Implemented `ServiceFactory` class in `factory.py` to create instances of services.
- Implemented `ServiceManager` class in `manager.py` to manage the creation and retrieval of services.
- Created `ServiceType` enum in `schema.py` to define the different types of services that can be registered with the service manager.
- Added `initialize_services` function in `manager.py` to initialize all the services needed.
The purpose of these changes is to provide a modular and extensible architecture for managing different services in the application. The `ServiceManager` allows for easy creation and retrieval of services, while the `ServiceType` enum provides a standardized way to refer to different types of services. The `Service` base class and `ServiceFactory` class provide a foundation for creating and managing specific services.
The following files and classes were removed:
- `src/backend/langflow/cache/__init__.py`: Removed unused import statements and `__all__` variable.
- `src/backend/langflow/cache/base.py`: Removed unused `BaseCache` class.
- `src/backend/langflow/cache/flow.py`: Removed unused `InMemoryCache` class.
- `src/backend/langflow/cache/manager.py`: Removed unused `Subject`, `AsyncSubject`, and `CacheManager` classes.
These files and classes were removed to clean up the codebase and remove unused functionality.
