perf(server/index.ts): do not set cookies to image proxy so CDNs can cache images

[lunks]

This is only a problem if CSRF protection is enabled.

Description

CDNs like Cloudflare bypass their cache if cookies are set in the response.
clearCookies middleware removes the header before imageproxy serves the image.

I initially considered creating a middlewares collection and removing CSRF protection from the list if it is present for the image proxy, but removing the header is a much simpler solution.

To-Dos

• Successful build yarn build
• Translation keys yarn i18n:extract
• Database migration (if required)

Issues Fixed or Closed

Curious why you are having cookies sent with your image proxy. I seem unable to reproduce. My images served through Cloudflare are returning hits for the cache.

If you enable CSRF, it gets set on every request. Cloudflare works fine if I disable CSRF, but I want the extra security the CSRF token provides.

Ah right CSRF. I see. Got it.
