feat: migrate to CoinAnk API and improve chart UI

- Chart improvements: professional styling, popular symbols quick selection, simplified B/S legend
- Data source migration: use CoinAnk API exclusively for all kline data
- Code cleanup: remove Binance WebSocket cache and related code (websocket_client.go, combined_streams.go, monitor.go)
- Log optimization: reduce hook spam, suppress 404 errors, increase P&L diff threshold
- Lighter integration: add order sync functionality, fix market order precision
- Remove ticker merge logic for simplicity
