Refactor Tooltip Timing and Enhance Dashboard Splitter Styles

- Reduced fade-out duration for tooltips from 500ms to 250ms and hide delay from 100ms to 10ms for improved responsiveness.
- Updated DashboardSidebarSplitter to include a new class for the content panel, enhancing layout flexibility and styling consistency.
- Adjusted CSS for cursor tooltip transitions to provide a smoother visual experience.
