#883 Clean up old frontend stuff

[pdelboca]

This is a PR to cleanup old parts of our frontend that are no longer relevant.

I tried to make isolated and descriptive commints, but I will add some extra details.

Details

• bee2cc5 is no longer needed since we do not need custom body attributes.
• 665f690 we are using Tailwind, so body classes are not required. Plus, those classes do not exist in our codebase anymore.
• de93899 we only have 1 compiled javascript asset. Custom blocks to render custom js is not required anymore
• head-alternate and head-links blocks are not required
• 2749fa0 template-js block is no longer needed. Carousel no longer exist and the slider functinoality is handled in our main js module.
• cef0287 We do not have breadcrumb in the site
• 92822ca django-compressor is not needed anymore. Our assets are compiled by npm.
• 137462b QUOTE_STYLE should have been cleaned in a previous cleanup: 6d1e9b2
