[MediaQueryProvider] Fix SSR hydration issues (#12824)

### WHY are these changes introduced?

Fixes #11886

Server-side rendering defaults to `isNavigationCollapsed` being `false`,
which causes a React hydration issue when rendered on the client at
smaller breakpoints (where the value evaluates as `true`).

### WHAT is this pull request doing?

This modifies the initial render state of `isNavigationCollapsed` to
match the server-side rendered value (`false`) and relies on the
existing `useEffect` to update the value on the client-side after
hydration.
