fix: resolve SL/TP order placement and orphaned cleanup issues

- Fixed Drift SDK initialization in place-order endpoint (NodeWallet vs Wallet)
- Added 2% minimum trigger distance validation in execute-drift endpoint
- Corrected orphaned order cleanup logic to cancel ALL orders when no position
- Resolved issue where SL/TP orders were immediately canceled due to insufficient distance
- Tested complete cycle: position entry → protective orders → orphaned cleanup

Orders now maintain proper 2% distance from market price and stay active.
Cleanup system correctly identifies and removes orphaned orders when positions close.
