fix: resolve IconButton onClick handler issue preventing clicks

The IconButton component was conditionally setting the onClick handler
based on the disabled state, which could prevent clicks from being
handled properly when onClick was undefined. The button now always
passes through the onClick handler and relies on the disabled attribute
to prevent clicks when disabled.

Fixes #7552
