Add /close command and auto-flip logic with order cleanup

- Added /close Telegram command for full position closure
- Updated /reduce to accept 10-100% (was 10-90%)
- Implemented auto-flip logic: automatically closes opposite position when signal reverses
- Fixed risk check to allow opposite direction trades (signal flips)
- Enhanced Position Manager to cancel orders when removing trades
- Added startup initialization for Position Manager (restores trades on restart)
- Fixed analytics to show stopped-out trades (manual DB update for orphaned trade)
- Updated reduce endpoint to route 100% closes through closePosition for proper cleanup
- All position closures now guarantee TP/SL order cancellation on Drift
