fix(planner): distinct aria-label for export dropdown toggle

The restyled Export split-button's dropdown toggle got aria-label
"Export GPX", colliding with the main button's text and breaking the
E2E selector that clicked the old "▾" glyph. Give it a dedicated
exportOptions label (en + de) and target it in the E2E test.
