feat: resolve project logo URLs server-side, show logos in admin + observer

Add attachProjectLogoUrls utility mirroring avatar URL pattern. Pipe
project.list and analytics.getAllProjects through logo URL resolver so
ProjectLogo components receive presigned URLs. Add logos to observer
projects table and mobile cards.
