feat: Telegram notifications for all 6 SSE events + hourly PnL summary

- Handle position_opened/closed/modified and order_placed/cancelled/modified
- Unified SsePayload struct (Option fields) for both position and order events
- Hourly PnL summary task (send_pnl_summary every 3600s, skip first tick)
- Add sim binary for testing TG notification flow without MT5
- Export telegram + helpers via lib.rs for bin access
- Update README with Telegram setup and event table
- Update .env.example with Telegram comment block
