feat: add real-time price fetching and fix data delays
- Add get_ticker() method for real-time quotes across all markets - Add get_realtime_price() service with ticker/kline fallback chain - Fix yfinance end date issue for US stocks and futures - Fix forex timezone parsing for Tiingo UTC timestamps - Add retry mechanism with exponential backoff for Tiingo API - Add API rate limiting for portfolio (3 concurrent, 0.3s interval) - Add force refresh option to bypass price cache on manual refresh
