Adding @types/qrcode to dev dependencies

[fantaJinMode]

Description

Moves @types/qrcode from dependencies to devDependencies, since type-only packages are only needed at build time and should not be shipped to consumers.

Why It Was Needed

Type definition packages (@types/*) are compile-time artifacts. Including them in dependencies causes them to be installed by downstream consumers unnecessarily, bloating their node_modules with packages that provide no runtime value.

Benefits

• Reduces consumer install size
• Aligns with standard Node.js package conventions for type-only packages
• Consistent with how other @types/* packages are already declared in this project

Type of Change

• 🐛 Bug fix (non-breaking change which fixes an issue)
• ✨ New feature (non-breaking change which adds functionality)
• 💥 Breaking change (fix or feature that would cause existing functionality to not work as expected)
• 📝 Documentation update
• ♻️ Code refactoring
• ⚡ Performance improvement
