The thumbnail upload (uploadProjectThumbnail) writes to a
'project-thumbnails' storage bucket, but instrumentation.ts only
bootstrapped the 'avatars' bucket. This caused:
Upload failed: Bucket not found
Add the missing bucket creation with matching constraints (public,
10 MB limit, image/png only). Also refactor the bucket-exists check
to use a Set so it scales cleanly as more buckets are added.
