feat(images): on-demand lanczos cover thumbnails for crisp grid/list

High-res covers (esp. line-art) looked jagged because the browser downscaled them to
the grid/list size. Downscale server-side with ffmpeg lanczos to a small cached WebP
instead. No re-upload/backfill: reads the existing original lazily on first request.

• services/ThumbnailService.js — ffmpeg lanczos downscale -> WebP, disk-cached
• server.js — GET /media/thumb/:w/* route (whitelist 320/480/640) before the /media static
• middleware/render.js — thumb(url,w) helper (rewrites local /media covers)
• views/partials/post-tile.ejs (grid 480) + post-card.ejs (list 320)
