Subject: [PATCH] Improve code auto-fix: prefer Qwen Coder with Hermes fallback

Update /api/fix-code endpoint to try MODEL_3 (Qwen Coder) first for
better code generation, with graceful fallback to MODEL_1 (Hermes) if
MODEL_3 is unavailable or returns errors.

This ensures the auto-fix feature works reliably even when specialized
code models are temporarily unavailable (e.g., 502 errors).
