Subject: [PATCH] feat: Enhance Drawer component with scroll locking
 functionality

- Added `lockScroll` prop to control body scroll behavior when the drawer is open.
- Implemented `lockScroll` and `unlockScroll` methods to manage overflow style.
- Ensured scroll is unlocked when the component is destroyed.
- Updated usage in SongFloatingToolbox to reflect the new prop.
