Add F-037, F-038, F-091 UI tests; mark F-016 red (no accessibility ID)

- F-037: Route preference cards (Direct/Scenic/Balanced) selectable
- F-038: Allow repeat cities toggle buttons work
- F-091: Date range filter sheet opens and applies correctly
- F-016: Marked RED - featured trip card buttons lack accessibility IDs
