[Refactor] Improve Data Node visual element (data tab)

[enarroied]

Description

The data_node selector has a show_data parameter, which allows to show the "Data" tab.
The visual element is "smart" and "knows" when data is tabular; in that case, the "DATA" tab has 2 sub-tabs: One for a table and one for charts.

There are 2 things I think could be improved with this visual element:

1- Add parameters to not show the charts (default to False). Sometimes this is not useful, and when it's not useful, it can be confusing (also, I imagine adding a chart element if not needed is not great for performance).

2- Add a "summary" tab or sub-tab with the "Data" tab. The idea is to display summary statistics of the table for each column (data type, min, max, mean, Q1/2/, number of missing values). I don't know how to do it, but the concept is similar to Kaggle's data card descriptions (one example: https://www.kaggle.com/datasets/artyomkruglov/gaming-profiles-2025-steam-playstation-xbox/data). Another example is VS Code's Data Wrangler extension for Jupyter notebooks: https://code.visualstudio.com/docs/datascience/data-wrangler-quick-start.
For point number 2, I would also add a parameter to add or remove this component.

Acceptance Criteria

• Any new code is covered by a unit tested.
• Check code coverage is at least 90%.

Code of Conduct

• I have checked the existing issues.
• I am willing to work on this issue (optional)

I really like your second point. For the first, I am not sure tha chart is built if you did not click on it

We would like to make the summary generic on tables as well. We have to detail the requirements.

Thank you for your great feedback.
