fix: Add direction-specific quality thresholds to docker-compose.yml

- Added MIN_SIGNAL_QUALITY_SCORE_LONG, _SHORT, and global to environment section
- Required for ENV variables to be available in Node.js process.env
- Without this, container couldn't read .env values for direction-specific thresholds

Testing verified:
- LONG quality 90: ✅ ALLOWED (threshold 90)
- SHORT quality 70: ❌ BLOCKED (threshold 95)
- Direction-specific logic working correctly
