Fix UpdateTimeframeData resilience - make pattern detection more robust

- Changed UpdateTimeframeData to not fail entire update if individual components fail
- Now considers update successful if ANY pattern detection works (OR logic vs AND logic)
- Bias calculation failures no longer cause entire timeframe update to fail
- This should eliminate the 'Failed to update multi-timeframe analysis' warnings
- Pattern detection will continue working even if bias calculation has issues
