Dataframes: by default, hide the row ID column

[abey79]

To some extent, row IDs are an implementation detail. Although they can occasionally be useful to display, they should be hidden by default.

#7453 introduce "All" vs. "Selected" choices of columns to display. One way to go about this would be to introduce a new, default choice "Recommended". Doing so would allow killing two additional birds with the same rocks:

• Dataframes: by default, hide empty columns #7459
• Dataframes: by default, hide indicator components #7460

This also tangentially relates to #7461, as display raw datastore rows slightly increases the importance of exposing row IDs (which are a proxy for "originated from the same log call"—caveat may apply).
