fix(ui): refine glassmorphism and page transition animations

- Added custom light/dark background images to replace unsplash URLs.
- Enhanced active sidebar item shadow and backdrop blur for better visibility.
- Fixed double loading flickers on user, node, group, and panel-sharing pages.
- Removed opacity transitions from AnimatedPage to prevent backdrop-filter rendering issues during page navigation.
