Restore Schedule inline-expand to match Angular (revert TIRREDESIGN-4 forward-ship)

The Schedule row had been switched to navigate-on-click in commit
a26adad as a forward-looking implementation of TIRREDESIGN-4. Angular
on the live test stand still uses inline-expand (verified 2026-04-23
on flights.test.aeroflot.ru — clicking a row toggles
.flight-list-item.selected and renders schedule-search-result-flight-
body / connecting-flight-body inline). React must not lead Angular —
restore the inline-expand wiring so both stays in lockstep.

Drops the schedule-specific branch in FlightList that disabled
expandable and wired onClick to navigate. The expand-via-onFlightClick-
or-renderExpandedBody rule applies uniformly to Board and Schedule
rows again, exactly like before commit a26adad.
