feat: image optimization — client-side resize + server-side thumbnails

Avatars/banners now resize to max 512px/1920px and convert to WebP before upload (zero server cost). Chat image uploads generate an 800px-wide WebP thumbnail via Sharp; the feed shows the thumbnail, click opens the full-res original. Adds lazy loading to avatars. Federation-compatible: remote instances without this feature fall back gracefully.
