TL;DR

fixes image transforms on the stack returning different images than the legacy backend, by giving the stack's imgproxy the same settings

what's Improved?

on the stack, supabase start ran imgproxy without the tuning the legacy backend passes it
a png requested by a browser that accepts webp came back as png instead of webp

animated gifs came back as a single frame, and large photos skipped the default 3000px size cap

fixed now by:

the stack's imgproxy now gets the same tuning as the legacy backend, so transforms return the same images on both
IMGPROXY_USE_ETAG is left out because imgproxy treats its legacy value like unset, so nothing changes there

🤖 AI Review

Both independent reviews completed with no findings. Reading both changed files and the legacy imgproxy configuration confirmed that the six settings match legacy values and the integration assertion checks WebP negotiation. No additional actionable issues found. Tests were not run during adjudication.
