Fix flaky DagRunsTab E2E test race condition in markRunAs

[choo121600]

Handle the case where the menu option becomes disabled while transitioning the dag run state between reading the state badge and opening the “mark-as” menu.
If the option is already disabled, close the menu with Escape and return early to prevent flaky tests.
