frontend: Use qobject_cast when casting QObjects

cg2121 · cg2121 · commit 5582ea1f2d22 · 2025-01-28T05:48:22.000-06:00
When casting between QObjects, qobject_cast should always be used.
This increases performance as there is no RTTI (Run Time Type Information)
with qobject_cast, like there is with dynamic_cast.
