Remove distribution tiles when distributions aren't computed
Follow up on https://github.com/skrub-data/skrub/pull/1255#issuecomment-2766633436. In the TableReport, when the number of columns is greater than some threshold, we don't compute or display marginal distributions.
Removing these tiles entirely could improve the TableReport further since tiles stats are already presented in the 'stats' panel in a more compact format.
This was addressed (partially) in #1340 for the expressions. From what I remember, the hang up was deciding where to display the message about having too many columns. By keeping the tabs, we can show it in there, without the tabs, we need to figure out where to put it.
What I was suggesting was keeping the "Distributions" tab and removing the individual tiles. The blue message can stay.
