[Feature Request]: allow keyboard navigation in pipeline and workflows

### What would you like to happen?

Migration: https://issues.apache.org/jira/browse/HOP-4477

in some scenarios, it would be faster to navigate through Hop Gui using the keyboard instead of the mouse 

For example, to make a couple of changes in a number of adjacent transforms, it would be faster to arrow-left, arrow-right to the next transform and e.g. hit space to change the transform's properties 

### Issue Priority

Priority: 3

### Issue Component

Component: Hop Gui

Start by reviewing the Hop Gui pipeline and workflow navigation described in the issue, along with the migration HOP-4477. Define the supported keyboard actions and their behavior across adjacent transforms and transform properties. Done means the requested navigation works consistently in both pipelines and workflows, with tests or verification steps identified for the affected GUI behavior.
