Expand Trowel Seed Equipping to 4 Types

Currently, players can equip up to two seed types for planting, even though the seed equipping modal has space for four. Expanding the seed equip limit to four types would enhance the planting process, allowing players to manage multiple crops more efficiently and make full use of the existing modal layout.

When sowing seeds on cultivated ground, players should be prompted to select which seed type they want to plant if more than one is equipped.
