Fix sidebar scroll position preservation during page navigation

- Replace unstable x-navigate:scroll directive with custom Alpine event handlers
- Use alpine:navigating event to save sidebar scroll position to localStorage
- Use alpine:navigated event to restore sidebar scroll position after navigation
- Sidebar now maintains scroll position when clicking document links
- Fixed 'Element not found' error that was preventing scroll restoration
- Uses requestAnimationFrame for smooth DOM restoration
