Enhance GridPlanner and GenerateGridDialog for improved slot management and user experience

Refactored the GridPlanner class to optimize slot management during grid generation, ensuring more efficient handling of slots. Updated the GenerateGridDialog component to improve its layout and usability, enhancing the overall user experience when interacting with slot lists. These changes contribute to better functionality and accessibility in grid management.
