🪲 BUG: Fix null reference errors in custom.js

- Add null checks before calling addEventListener on sidebar-true and sidebar-false elements
- Prevents 'Cannot read properties of null' error when elements don't exist in DOM
- Applied fix to both docs/assets/custom.js and template/assets/js/custom.js
