refactor: align favicon tool with Calculate/Media blueprint
- FaviconGenerator: lg:grid-cols-5 layout (2/5 setup, 3/5 results);
glass panels, native inputs, custom tab switcher (Icons/HTML/Manifest),
native progress bar, empty state placeholder, mobile Setup|Results tabs
- FaviconFileUpload: remove shadcn Button; match media FileUpload styling
with file card, metadata chips (size, dimensions)
- CodeSnippet: remove shadcn Button; dark terminal (#06060e) with hover
copy button, consistent with ASCII/ExportMenu code blocks
