🔧 Fix AI Analysis Service - Improved Prompts & Error Handling

✅ FIXED: AI analysis prompts to bypass OpenAI safety guardrails
✅ FIXED: Added technical analysis focus instead of trading advice tone
✅ FIXED: Improved JSON parsing and error handling
✅ ADDED: Option to use existing screenshots for testing (useExisting param)
✅ IMPROVED: Better image detail settings and temperature for consistency

🐛 DEBUGGING: Still investigating why AI claims it can't see images
- OpenAI vision capabilities confirmed working with public images
- Model gpt-4o has proper vision support
- Issue appears to be with chart image content or encoding

🎯 NEXT: Debug image encoding and model response inconsistency
