Fix the Control UI Set Default action to persist agents.list[].default instead of the unsupported agents.defaultId config key.\n\nCloses #65565.\n\nThanks @luyao618.
Add the existing desktop cron-session visibility toggle to the mobile chat settings dropdown, reusing the shared session filtering state and cron filter icon path.
Also add focused browser render coverage for the mobile dropdown so the cron filter button, hidden-count title, active/pressed state, and click behavior are covered.
