Add robust fallback logic for Step 3 data passing

- Check multiple storage sources for website URL (props, localStorage, sessionStorage)
- Add validation to prevent API calls without website URL
- Improve debugging logs to track data flow
- Make CompetitorAnalysisStep more resilient to production edge cases
- No breaking changes, just defensive improvements
