fix: Ensure FAQ heading synchronization reacts to inner block changes

Updates the `useSyncQuestionHeadingLevels` hook to explicitly select the inner
FAQ question blocks using `useSelect`. By including these blocks in the
`useEffect` dependencies, heading levels are now correctly re-synchronized
when questions are added, removed, or reordered within the FAQ block.
