[FIX] حل مشکل ModuleNotFoundError peikarband.peikarband در Docker (fix) | ApprovalToken: accepted

- ایجاد peikarband/__init__.py برای فعال‌سازی package
- ایجاد peikarband/peikarband.py برای export کردن app
- تغییر Dockerfile برای حفظ ساختار peikarband package در /build/peikarband/ و /app/peikarband/
- به‌روزرسانی مسیرهای reflex commands و REFLEX_DIR
- این تغییرات باعث می‌شود Reflex بتواند peikarband.peikarband را پیدا کند
