Cannot update group icon due to CORS issue

[pyxfluff (Pyx)]

The CORS (yuck) header for the group icon upload endpoint is missing OPTIONS, so Firefox refuses to send the request.

Browser version string: Mozilla Firefox for Arch Linux; archlinux - 1.0; 145.0a1 (2025-09-20) (64-bit)

Workaround: Use a CORS unblocker

Thank you for documenting - we will investigate.
