🔧 Fix Text-to-Video Timeout Issues

## 🛠️ Critical Timeout Fixes
- Increased base timeout from 5 to 15 minutes (more realistic)
- Reduced status check interval from 10s to 5s (better UX)
- Fixed timeout multipliers to be less aggressive

## 🔄 API Status Handling Improvements
- Added support for Novita's TASK_STATUS_* format
- Handle TASK_STATUS_PROCESSING, TASK_STATUS_SUCCEED correctly
- Improved status mapping for better reliability

## 💡 User Experience Enhancements
- Better timeout estimates and messaging
- Real-time elapsed time display
- More informative status messages
- Clear guidance for users during generation

## 📊 New Timeout Calculations
- Lite models (720p, 5s): ~18 minutes max
- Pro models (1080p, 10s): ~37 minutes max
- More realistic timeouts prevent premature failures

This should resolve the text-to-video timeout issues.
