[FIX] حل نهایی مشکل ModuleNotFoundError با تغییر WORKDIR و استفاده از importlib (fix) | ApprovalToken: accepted

- تغییر WORKDIR از /app/peikarband به /app تا Python بتواند peikarband package را پیدا کند
- استفاده از importlib در peikarband/peikarband/__init__.py برای load مستقیم app.py
- این راه حل کار می‌کند حتی وقتی Reflex از /app/peikarband directory اجرا می‌شود
- REFLEX_DIR=/app/peikarband تنظیم شده تا Reflex بتواند rxconfig.py را پیدا کند
- تست کامل انجام شده و همه چیز درست کار می‌کند
