Move custom status-page design into Upptime config so it survives auto-deploys

Upptime's site.yml rebuilds and force-deploys the whole static site on a
schedule, which was wiping out design changes made directly to the built
gh-pages output. assets/ contents are copied verbatim over the generated
site on every build, so placing the custom global.css, theme CSS, and
status-icon-fix.js there (wired up via .upptimerc.yml) makes the design
part of the generated output instead of something to manually restore.
