Adds shared/preview-lib.js with two cross-tool renderers:
- renderTiff (UTIF.js, lazy-loaded from CDN; PDF-style toolbar with
page nav, zoom, fit-width/fit-page; multi-page TIFFs decode lazily)
- renderZipListing (JSZip; sortable name/size/modified table, sticky
header, host-grouped paths)
Wired into the four tools that have a preview surface (archive, classifier,
mdedit, transmittal). Cross-document compatible so the same renderer works
for popup-window tools (archive/classifier/transmittal) and inline tools
(mdedit). Archive previously had no image branch at all — now previews
JPG/PNG/GIF/WebP/BMP/SVG natively, plus TIFF via UTIF, plus the ZIP listing.
Adds the dark-blue rounded-square favicon to each app's header (left of
the title) and to the website navigation. Single inline SVG, sized via
.app-header__logo (in shared/base.css) for tools and .brand-logo (in
website/css/style.css) for the website. Self-contained — the SVG carries
its own background, no wrapper styling needed.
