Search/Usages result preview window has an extreme mouse wheel property (>=4 movements total?)

### Apache NetBeans version

Apache NetBeans 28

### What happened

Search or Usages results preview windows has its own hardcoded value for mouse wheel up and down movement and is extreme, One mouse wheel movement and it jumps to a relative position (about total lines/ 4) and it is not predictable. This should not happen, it should at least inherit the main editor behavior.

Reproduce the issue in Apache NetBeans 28 on Windows 11 by running Find/Search or Find Usages, selecting a result, and scrolling in the preview window. Locate the preview's mouse-wheel handling and compare it with the main editor behavior. Done means preview scrolling uses a predictable increment consistent with the main editor instead of jumping by roughly a quarter of the content.
