Allow Early Extension of Additional Farm Plot Rentals

Players renting additional farm plots can currently only renew them once the rental period expires, which could disrupt farming schedules. I’m also unsure what happens to harvestable crops if the rental expires—do they die, or can players still collect them within a limited window?

It would be helpful to allow players to extend rentals before expiration. If the maximum rental period is one week, players could extend the rental based on the remaining days, ensuring more consistent farming and crop management.
