Fix search: remove conflicting bibsearch.js module listener on publications page

bibsearch.js and the inline script both attached input listeners to #bibsearch,
causing them to fight — bibsearch.js used CSS.highlights/.unloaded while the
inline script used display:none, resulting in no visible filtering.

Fix: replace liquid include with a plain <input id='pub-search'> so bibsearch.js
never loads on this page; inline script now owns the element exclusively.
