Brandon LiandClaude Opus 5 d1e8668440 Let the extension update itself, and host the dashboard
Chrome has no update channel for an unpacked extension, so every pull left one
manual step: click reload on its card. The dashboard now publishes the version
its own checkout ships at /api/autobuyer/status, and the extension reloads
itself when it is behind — chrome.runtime.reload() re-reads the folder from
disk, which the update check has already pulled into. It only ever runs code
that is on disk, so a reload that changes nothing is reported and waited out
rather than repeated; a dashboard that is behind is ignored.

Also adds the deploy stack for running the dashboard on the droplet, next to
the autotrader one: it joins that nginx's network and renders a server block
into its conf.d rather than standing up a second ingress. AUTOFIRMER_DB moves
the SQLite file onto a volume, since the working directory in a container is
replaced on every deploy.

And waitFor gained `hidden`: an absent gate matched on DOM presence only, so a
modal that closes by going display:none could never satisfy it. The extension
grew a visibility probe for this — locate cannot answer it, because absent and
hidden are both errors there and a wait gate has to tell them apart.
