critical: Prevent hedge positions during signal flips

**The 4 Loss Problem:**
Multiple trades today opened opposite positions before previous closed:
- 11:15 SHORT manual close
- 11:21 LONG opened + hit SL (-.84)
- 11:21 SHORT opened same minute (both positions live)
- Result: Hedge with limited capital = double risk

**Root Cause:**
- Execute endpoint had 2-second delay after close
- During rate limiting, close takes 30+ seconds
- New position opened before old one confirmed closed
- Both positions live = hedge you can't afford at 100% capital

**Fix Applied:**
1. Block flip if close fails (don't open new position)
2. Wait for Drift confirmation (up to 15s), not just tx confirmation
3. Poll Drift every 2s to verify position actually closed
4. Only proceed with new position after verified closure
5. Return HTTP 500 if position still exists after 15s

**Impact:**
-  NO MORE accidental hedges
-  Guaranteed old position closed before new opens
-  Protects limited capital from double exposure
-  Fails safe (blocks flip rather than creating hedge)

**Trade-off:**
- Flips now take 2-15s longer (verification wait)
- But eliminates hedge risk that caused -4 losses

Files modified:
- app/api/trading/execute/route.ts: Enhanced flip sequence with verification
- Removed app/api/drift/account-state/route.ts (had TypeScript errors)
