Fix the dashboard CSS cascade: hero-actions specificity and the 55rem stack

app.css loads after spry.css, so the re-proportioned .dash-board columns
would have out-ranked the framework's own 55rem stacking rule inside its
@media block (media queries add no specificity) - the stacking is
restored in the goal-41-task-3 section. The advisor-hero-actions
override now matches the goal-27 rule's specificity so the later rule
wins the tie without editing the earlier section.
