fix: localStorage key consistency for Safe Paper Trading positions

- Fixed conflicting localStorage keys causing positions to disappear
- Added backward compatibility to load from both old and new key patterns
- Standardized to safePaperTrading_ prefix for consistency
- Updated reset function to clear all key patterns
- Positions should now persist when navigating between pages
