Adds 530 decorations in 19 new categories (631 total). Decorations that
contain Discord branding (the Clyde-visor helmets) are excluded.
The decorations are ~1 MB animated PNGs, so a picker that rendered every
one would pull ~590 MB while scrolling. The picker now:
- shows static 144px WebP thumbnails (~9.5 KB each, `thumbs/` on the CDN)
and loads the animated file only on hover, focus or selection, with a
fallback to the full file if a thumbnail is missing;
- mounts one category at a time behind tabs, plus a name search across
all categories.
scripts/makeDecorationThumbs.py builds the thumbnails from the busiest
frame of each animation (many start on an empty frame).
