feat(categories): icons for parking, bus stops, stations, airports and fuel (#2706)

The category picker had no icon to tell a car park or a terminal apart from the
places a trip visits. Five transport icons join the shared table, which the admin
pickers, map pins and the PDF all read; the ship's tooltip now also says ferry.
