Refactor GrooveControls component for improved UI and user experience

Commit notes

This commit simplifies the GrooveControls component by updating the layout and enhancing the slider functionality. The groove type and description logic has been removed in favor of a more streamlined display, focusing on a single slider with clear labels for "Rush" and "Drag." Additionally, the styling has been adjusted for better visual clarity. These changes aim to enhance user interaction with groove settings in the sequencer.
