fix: standardize exchange database path to use centralized data directory with environment variable

🔧 Database Path Standardization:
• Change DATABASE_URL environment variable to EXCHANGE_DATABASE_URL
• Update default database path from ./exchange.db to /var/lib/aitbc/data/exchange/exchange.db
• Apply consistent path resolution across all exchange database connections
• Update database.py, seed_market.py, and simple_exchange_api.py with new path
• Maintain backward compatibility through
