refactor(core): restructure chat models and services, integrate route-based chat IDs

- Updated `Chat` and `ChatMessage` models for new table structures with UUIDs and attributes.
- Integrated `ChatPolicy` for authorization checks.
- Updated `ChatMessageController` with authorization and refined logic.
- Adjusted routes and state in the frontend to handle chat IDs from the URL.
- Enhanced `SocialMediaService` for handling chat-specific user prompts.
- Removed unused migrations related to chats and chat messages.
