Fix WordNet service 502 error in production deployment

ISSUE IDENTIFIED:
- Production deployment sets PORT=3005 for WordNet service
- Nginx proxy routes /wordnet to wordnet-service:3005
- But WordNet service was hardcoded to port 3003
- This caused 502 Bad Gateway errors in production

SOLUTION:
- Make WordNet service respect PORT environment variable
- Default to port 3003 for development, use PORT env for production
- Update log messages to show dynamic port

The service now works correctly in both:
- Development: runs on port 3003 (default)
- Production: runs on port 3005 (from PORT env var)

This fixes the 502 error when nginx proxy forwards /wordnet requests.
