[Improved, Fixed] Logo stability & optimization

Improvements

• Company logos are now routed through Classet’s image optimizer, delivering faster load times and consistent WebP files for every visitor
• Logos hosted on brandbadge.clearbit.com are now whitelisted, so they display without extra configuration
• Existing SVG logos will be automatically converted to WebP in an upcoming background backfill, bringing them in line with the new optimization pipeline

Fixes

• Resolved a critical issue that prevented all new logo uploads and returned a 500 error; recruiters can once again upload or update company logos without failures
