Stop upptime from wiping our custom design every time it auto-deploys

Every time upptime's site workflow ran, it rebuilt the status page from
scratch and overwrote whatever design changes we'd made directly on the
gh-pages branch, so someone had to keep manually re-applying the design
after every bot commit.

Turns out upptime copies anything in assets/ straight into the built
site, and .upptimerc.yml can inject custom CSS/JS through it. So instead
of hand-editing the generated output, our global.css, theme colors, and
the status-icon-fix script now live in assets/ and get pulled in on
every rebuild automatically - no more manual restoring after each deploy.
