* refactor: replace presigned URL uploads with backend upload endpoints
* feat: update avatar upload to use new endpoint
* refactor: use createS3Client in auth hooks
* feat: generate presigned URLs for avatars
* fix: show avatar image in user menu
* fix: hide tooltip if content is empty
* fix: support external avatar URLs in generateAvatarUrl
* fix: remove content type restriction on attachments
Avatar images failed to load with 403 on Tigris and newer AWS S3 buckets
because getAvatarUrl only constructed path-style URLs. Modern S3-compatible
providers require virtual-hosted URLs (bucket.domain/key).
Add NEXT_PUBLIC_STORAGE_DOMAIN env var to signal URL style:
- If set: virtual-hosted URL (Tigris, AWS S3)
- If not set: path-style URL (MinIO, LocalStack) - backward compatible
Add vitest and tests for getAvatarUrl behavior.
