Improve error handling and API efficiency

Browse Source 
- Switch to safe*() methods for centralized error handling
- Add error handling and validation
- Optimize radar API usage by only fetching yesterday's data when needed
- Use centralized URL rewriting for caching proxy support
- Add debug logging throughout radar processing pipeline
- Improve canvas context validation and error recovery
- Handle worker errors gracefully by setting totalScreens = 0 to skip in animation
- Remove unused OVERRIDES parameter passing to workers
