[HUD] Fix SLI page scroll reset and navigation hijacking (#6945)

Fix SLI page navigation and scroll issues

This PR fixes two issues on the /sli page:

  1. Scroll position was locked at the top of the page
2. Navigation hijacking: Clicking navbar links would briefly navigate
away but then immediately return to /sli

  Changes:

- Added shallow: true to router.push() to prevent full page re-renders
when updating URL parameters
- Added pathname check to prevent the useEffect from running when
navigating away from the page
