fix: auto-expand and auto-scroll for actions logs (#35570) (#35583)

Implements reliable auto-expand and auto-scroll behavior for the Actions
logs view.

* Expands running or unfinished steps automatically.
* Smoothly scrolls to the latest log line during execution.
* Controlled via existing “Always auto-scroll” and “Expand running
steps” options.

Fixes #35570.
