Subject: [PATCH] Default schedule day groups to collapsed

Match Angular's p-accordion default-collapsed state on the schedule
results page. State now tracks expanded days (default empty)
instead of collapsed days (default empty), so the initial render
shows day headers only and the user clicks to reveal flights.
