feat: optimize Interactive training page performance using cached user data

- Created useTrainingData hook to eliminate redundant API calls
- Leverages cached user authentication data instead of separate fetches
- Replaced fetchCompanyData() with optimized SWR-based data fetching
- Uses parallel API calls with Promise.allSettled for better performance
- Implements optimistic cache updates for persona modifications
- Addresses same performance concerns as issue #113 in main web app

Performance improvements:
- Eliminates duplicate persona and external sources API calls
- Uses existing user/company context from authentication
- Implements proper loading states and error handling
- Maintains real-time data consistency with SWR caching
