merge: integra fase5 do Thiago (DOM, VWAP, big trades, trading, historical browser) mantendo fixes de ontem

- Combina on_history_ready_callback (replay reset) com on_big_trade_callback (Thiago)
- DOM subscription + visualização no canvas
- VWAP e delta profile no volume profile
- Big trades com alerta visual no canvas
- Endpoints /trade/buy, /trade/sell para execução via MQL5
- Historical Browser: date picker no header, /history/load e /history/live
- Trading panel no sidebar com botões BUY/SELL
- config/settings.py: mantém USTEC como padrão, adiciona BIG_TRADE_THRESHOLD
- Todos os fixes de ontem preservados: broadcast live, history_ready, replay reset
