feat: use market_outlook to adjust BUY confidence threshold (#173)

- Import MarketOutlook at module level in main.py
- After scenario evaluation, check market_outlook and apply BUY confidence
  threshold: BEARISH→90, BULLISH→75, others→settings.CONFIDENCE_THRESHOLD
- BUY actions below the adjusted threshold are downgraded to HOLD with
  a descriptive rationale including the outlook and threshold values
- Add 5 integration tests covering bearish suppression, bearish allow,
  bullish allow, bullish suppression, and neutral default threshold

Closes #173
