feat(images): downscale remote (fediverse) avatars via a signed proxy

Remote avatars live on other servers, so the browser shrank full-res line-art to ~44px
(jagged). Fetch them once (SSRF-safe via safeFetch), downscale identically (lanczos -> WebP),
cache, serve. HMAC-signed proxy URLs → not an open resizer.

• services/ActivityPubService.js — export safeFetch
• services/ThumbnailService.js — getRemoteThumbnail + signed imgProxyUrl/verifyImg; +128px size
• server.js — GET /img/a/:w signed proxy route
• middleware/render.js — avatar(url,w) helper (local thumb / remote proxy)
• views: news.ejs, fedi-node.ejs, following.ejs avatars -> avatar()
