Add chat deletion endpoints and handlers in Neo API

- Introduced new API endpoints for deleting individual chats and clearing all chats for a user, enhancing chat management capabilities.
- Implemented handleChatDelete and handleChatsDeleteAll methods to process deletion requests, including error handling for missing session and chat IDs.
- Updated API router to register new endpoints under the 'dangerous' path, ensuring clear separation of critical operations.
- Enhanced overall API structure and maintainability by adding robust feedback mechanisms for deletion operations.
