🎯 MAJOR RELEASE v1.3.0 - Complete OCO System Overhaul

🚨 CRITICAL OCO FIXES - UPDATE IMMEDIATELY

This is a major release that completely fixes the broken OCO (One-Cancels-Other) order system that has been non-functional since deployment.

🐛 Critical Issues That Were Fixed

1. 🔴 OCO Order Creation Broken

• Problem: profit_order_id and stop_order_id were never properly extracted from Binance API responses
• Result: Database had empty IDs, making surveillance impossible
• Fixed: Enhanced ID extraction with detailed logging and error handling

2. 🔴 OCO Surveillance Non-Functional

• Problem: Bot could never detect when OCO orders were executed
• Result: Orders showed as 'ACTIVE' forever, even after execution
• Fixed: Multi-method surveillance (open orders + historical analysis)

3. 🔴 Future Transfer Logic Inverted

• Problem: sell_ratio = (100 - profit_target) / 100 → Sold 97%, kept 3%
• Impact: Completely opposite of intended accumulation strategy
• Fixed: sell_ratio = profit_target / 100 → Sell 3%, keep 97%

🔧 Complete System Rebuild

📊 New OCO Surveillance System

🔍 Multi-Method Verification:
1. Check open orders first (real-time status)
2. Search historical orders (24h lookback)  
3. Analyze order statuses (FILLED/EXPIRED/CANCELED)
4. Update database automatically

✅ Enhanced OCO Creation

# Before (broken)
profit_order_id = None  # Always stayed None
stop_order_id = None    # Always stayed None

# After (fixed)
profit_order_id = extracted_from_api_response  # ✅ Properly extracted
stop_order_id = extracted_from_api_response    # ✅ Properly extracted
# + Detailed logging and error handling

🎯 Corrected Accumulation Strategy

Aspect	Before (Wrong)	After (Correct)
Buy	1.0 BTC	1.0 BTC
Sell for profit	0.97 BTC (97%) ❌	0.03 BTC (3%) ✅
Keep for accumulation	0.03 BTC (3%) ❌	0.97 BTC (97%) ✅
Strategy result	No accumulation ❌	Proper accumulation ✅

🎉 User Impact

✅ What Works Now

• OCO orders create properly with all IDs recorded
• Automatic detection when orders execute (profit or stop-loss)
• Database stays synchronized with Binance reality
• Dashboard shows accurate OCO statuses
• Proper accumulation strategy (keep most, sell small portion)

📊 What You'll See

Before: 🌍 Achats aujourd'hui: 4/100 | 🎯 OCO Actifs: 4 (but all broken)
After:  🌍 Achats aujourd'hui: 4/100 | 🎯 OCO Actifs: 2 (accurate count)

OCO Status Updates:
- 'ACTIVE' → 'PROFIT_FILLED' (when profit taken)
- 'ACTIVE' → 'STOP_FILLED' (when stop-loss hit)  
- 'ACTIVE' → 'EXPIRED_OR_CANCELED' (when expired)

🔄 Automatic Migration

1. Check all existing 'ACTIVE' OCO orders against Binance
2. Update statuses for orders that were actually executed
