[FIX] حل مشکل ModuleNotFoundError با حذف peikarband.py و استفاده از __init__.py (fix) | ApprovalToken: accepted

- حذف peikarband.py که با peikarband/ directory تداخل داشت
- به‌روزرسانی __init__.py برای ایجاد peikarband.peikarband submodule
- به‌روزرسانی PYTHONPATH در Dockerfile برای پشتیبانی از src.* imports
- این تغییرات باعث می‌شود Reflex بتواند peikarband.peikarband را پیدا کند
