Fixed sticky title and author hover JS (#629)

no issue

- replaces author hover JS that was lost during merge
- replaces `floating-header.js` with `sticky-nav-title.js` containing the relevant JS that was lost during merge with a cleanup for unused variables and unnecessary event listeners
- removes reference to non-existent `{{> floating-header}}` partial
