ENH: Update Q_PROPERTIES with CONSTANT specifier for Qt best practices

hjmjohnson · hjmjohnson · commit 8bf486f44099 · 2025-07-14T14:54:23.000-05:00
For improved compliance and to address warnings, marked read-only Q_PROPERTIES as CONSTANT across multiple modules, ensuring adherence to modern Qt conventions.
