refactor: enhance chat page greeting display and input focus management

- Introduced caching for greeting names to improve user experience during chat interactions.
- Updated greeting display logic to ensure proper visibility based on user state.
- Added a pending focus mechanism in the chat input to manage focus requests more effectively.
- Refactored layout and animation handling for a smoother greeting presentation.
- Improved overall responsiveness and state management in the chat page.
