The install read the generated LiveKit credentials with a plain grep, but
secrets.env is chmod 600 and owned by the docker install user while the hooks
run as the manager — so the read returned nothing, the hook errored out, and
Caddyfile and livekit.yml were never written. Compose then refused to start,
because a bind mount whose source does not exist is not a soft failure.
Read secrets through runFileOp, and reorder so the Caddyfile and the three
URL-bearing files are written first: any step that can fail now comes after
every mount source already exists. The missing LiveKit keys are downgraded from
fatal to a warning for the same reason — losing voice is worth reporting, but it
is no reason to take the other fifteen services down with it.
