CRITICAL FIX: Prevent unprotected positions via database-first pattern

Root Cause:
- Execute endpoint saved to database AFTER adding to Position Manager
- Database save failures were silently caught and ignored
- API returned success even when DB save failed
- Container restarts lost in-memory Position Manager state
- Result: Unprotected positions with no TP/SL monitoring

Fixes Applied:

1. Database-First Pattern (app/api/trading/execute/route.ts):
   - MOVED createTrade() BEFORE positionManager.addTrade()
   - If database save fails, return HTTP 500 with critical error
   - Error message: 'CLOSE POSITION MANUALLY IMMEDIATELY'
   - Position Manager only tracks database-persisted trades
   - Ensures container restarts can restore all positions

2. Transaction Timeout (lib/drift/orders.ts):
   - Added 30s timeout to confirmTransaction() in closePosition()
   - Prevents API from hanging during network congestion
   - Uses Promise.race() pattern for timeout enforcement

3. Telegram Error Messages (telegram_command_bot.py):
   - Parse JSON for ALL responses (not just 200 OK)
   - Extract detailed error messages from 'message' field
   - Shows critical warnings to user immediately
   - Fail-open: proceeds if analytics check fails

4. Position Manager (lib/trading/position-manager.ts):
   - Move lastPrice update to TOP of monitoring loop
   - Ensures /status endpoint always shows current price

Verification:
- Test trade cmhxj8qxl0000od076m21l58z executed successfully
- Database save completed BEFORE Position Manager tracking
- SL triggered correctly at -$4.21 after 15 minutes
- All protection systems working as expected

Impact:
- Eliminates risk of unprotected positions
- Provides immediate critical warnings if DB fails
- Enables safe container restarts with full position recovery
- Verified with live test trade on production
