[Feature Request]: Add a database widget to Hop gui

### What would you like to happen?

What would you like to happen?

There are certain environments were it's not possibl to use a DB client to see the data pre and post execution.
However, you can explore the DB from within the DB connection inside the metadata tab.
The functionality is already there, a db widget that can be easily accessed could allow Hop users to perform the same tasks they already have access to without need ing to leave the ui and into another tool or by accessing the functionality after several steps.

The old tool had a an entry under Tools just above "clear db cache" now that's deep within the metadata perspective.

### Issue Priority

Priority: 3

### Issue Component

Component: Hop Gui

Start by reading the Hop GUI code for the metadata tab and the existing database exploration functionality, then compare it with the old Tools entry above “clear db cache.” Define the widget’s access point and verify that users can perform the same database exploration tasks directly from the GUI without navigating through the metadata perspective.
