There was no ordering on a query returning dag_runs when it comes
to grid view. This caused flaky tests but also it would have
caused problems with random reordering of reported dagruns in the
UI (it seems).

This change adds stable ordering on returned Dag Runs:

  • by dag_run_id (ascending) asc

No need to filter by map_index as there will be always max one
returned TI from each dag run

cc: @ashb -> I think you need to take a look, but I am quite certain it was it.

You might want to include @ashb (if not done already) in #24284

The PR is likely OK to be merged with just subset of tests for default Python and Database versions without running the full matrix of tests, because it does not modify the core of Airflow. If the committers decide that the full tests matrix is needed, they will add the label 'full tests needed'. Then you should rebase to the latest main or amend the last commit of the PR, and push it with --force-with-lease.
