Refactor server and API handler for improved error handling and routing logic. Updated request handling to use Incoming type and added HTTP/1.1 restriction. Enhanced splash screen logic in the frontend to manage routing based on onboarding and setup states. Fixed WebSocket client initialization to ensure lazy loading and error handling. Cleaned up unused imports and variables across multiple files.
