fix(js): remove dead testimonialSlider/flexslider call from scripts.js

After the flexslider asset removal, scripts.js still tried to call
$('.testimonialSlider').flexslider(...) which threw a TypeError in the
browser console on every page. The element does not exist in this
rebuild and never will — testimonials were a feature of the original
Grav theme that we are not porting. Hero carousel and employees
carousel are both Bootstrap-3, auto-initialized via data-ride.

No functional impact on the page (every initializer before this block
already ran), just a noisy console error.
