compose: point caddy's /srv/homepage at the host dir, not the repo

The caddy container mounted the repo's shared/homepage (the static source) to
/srv/homepage. But the deploy writes the generated files (status.json from the
status checker, deployed.js from the deploy) to the host's /srv/homepage. So
the container served the static files (200) but 404'd the generated ones.
Mount the host's /srv/homepage instead, which holds both the static files (the
deploy copies them) and the generated ones.
