fix: smaller publication circles, author avatar fallback, DID from documents
- reduce radius multiplier from 0.5 to 0.35, cap at 28px
- extract DID from document metadata when turso lookup misses
- batch-fetch author avatars from bsky public API at build time
- atlas.js: prefer coverImage, fall back to avatar URL
