Maybe display both "plan rows" and "actual rows" in analyze output

Postgres/edgedb reports both "plan_rows" (the number of estimated rows returned by a node in the plan tree) and "actual_rows" (the actual number of rows returned)

It looks like the CLI only displays actual_rows if present, otherwise plan_rows, even in `\expand`d mode. The distinction is not always useful, but it's sometimes important to make sense of confusing behaviors like reported in https://github.com/edgedb/edgedb/issues/5879

It might also be useful to have a displayed hint that `\expand` can be run for more detailed output.
(I don't know if I have ever been satisfied by the non-expanded output.)

Start at the CLI's analyze output and compare the normal and \expand modes, focusing on how plan_rows and actual_rows are selected for display. Confirm the desired output with the reported Postgres behavior; done means the row estimates and actual counts are distinguishable and any \expand hint has a clear, tested condition.
