fix: resolve syntax issues in recommendation flow

[nirvani-nj]

Summary [required]

This PR fixes multiple syntax issues in static/script.js that were breaking the recommendation flow on the homepage.

The malformed JavaScript prevented the file from parsing completely, which caused skill chip input, autocomplete suggestions, quick-pick interactions, and recommendation form submission to stop working. The PR cleans up the broken submit handler and fixes the malformed renderResults() logic to restore normal frontend behaviour.
