[FIX] حل مشکل rxconfig.py not found و peikarband.peikarband import (fix) | ApprovalToken: accepted

- تغییر WORKDIR به /app/peikarband تا Reflex بتواند rxconfig.py را پیدا کند
- اضافه کردن کد در peikarband/__init__.py برای ثبت peikarband.peikarband در sys.modules
- این کد peikarband.peikarband را به صورت خودکار load می‌کند وقتی peikarband package import می‌شود
- تست کامل انجام شده
