Refactor FloatingGenerateBox and StoriesTab for improved layout and interaction

- Adjusted FloatingGenerateBox positioning to align with the story list, ensuring consistent UI across different routes.
- Modified StoriesTab layout to enhance responsiveness, including setting a maximum width for the story list and adjusting the right column for better content display.
- Streamlined StoryChatItem interaction by simplifying the play functionality, allowing double-click to trigger playback directly from the text area.
- Enhanced StoryContent component by cleaning up unused playback controls and improving overall structure for better readability.
