[Arvion] Security remediation: Upgrade dependencies and apply Python 3 compatibility fixes

[arvion-bot-dev-felipe2]

Automated Security Remediation

📂 Files Modified

• setup.py

  • Updated the version numbers for all dependencies in install_requires to the target versions specified in the migration plan. The python_requires directive was also updated from Python 2.7 to >=3.8 to support the new versions of critical dependencies like Flask and SQLAlchemy, which are not compatible with Python 2.

• app/database.py

  • Updated app/database.py for compatibility with SQLAlchemy 2.0 and Python 3. This involved importing and using text() from SQLAlchemy for raw SQL queries, as session.execute no longer accepts plain strings. Python 2-specific code, such as the __unicode__ method and checks for the unicode type, were updated to their Python 3 equivalents (__str__ method and str/bytes types).
