Removed redundant constraint for Python version

[Guiorgy]

Since the minimum supported Python version is 3.9, from the README:

Prerequisites

1. Install Node.js 20 and above (https://nodejs.org/en/download)
2. yarn (https://yarnpkg.com/getting-started/install)
3. Python 3.9 and above (https://www.python.org/downloads/)
4. PostgreSQL server (https://www.postgresql.org/download)

The constraint python_version >= '3.9' should be redundant, no?

Walkthrough

Removed Python version constraint from qrcode[pil]==8.* dependency in requirements.txt. The package is now required for all Python versions instead of being conditional for Python 3.9 and above.

53-53: Constraint removal is safe but consider documenting the rationale.

The python_version >= '3.9' constraint on qrcode[pil]==8.x is technically redundant. PyPI metadata confirms qrcode 8.2 requires >=3.9,<4.0, which matches the project's minimum Python version of 3.9. Removing this constraint poses no immediate risk to dependency resolution.

However, explicit version constraints serve as documentation and provide a safety margin if project requirements change in the future. Consider adding a comment explaining why the constraint was removed, or keep it as a redundant but defensive measure.
