Add new JSON data file and enhance simulation management features

- Introduced a new JSON data file containing detailed actions and quotes related to the 武大声誉修复基金 initiative.
- Updated the OasisProfileGenerator to ensure compatibility with the new JSON format, emphasizing the inclusion of user_id.
- Modified simulation management to support independent tracking of Twitter and Reddit platforms, including completion status and round information.
- Enhanced the SimulationRunner to accurately reflect the completion state of each platform and added checks for overall simulation completion.
- Improved the GraphPanel and Step3Simulation components to provide real-time updates and better user feedback during simulations.
