Monitoring moved to a dedicated Upptime repo at StarTrail-org/status. The old setup with a `status` branch in this repo didn't work because Upptime's summary generator queries the default branch for commit history, not the data branch. Removes: uptime workflows, .upptimerc.yml, status-site/. Keeps: web/lib/uptime.ts (may be repointed to the new repo later).
