Fix for UnicodeDecodeError on Macbook

[unipheas]

On first install using a MacBook M1 Max running Tahoe 26.3, after installing all dependencies through brew, I got this error when running sudo python3 intercept.py

Traceback (most recent call last):

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbb in position 0: invalid start byte

This PR is adding load_dotenv=False to app.run to resolve UnicodeDecodeError
