Keep the dev bind mounts out of CI, where they land nowhere

compose.dev.yml mounts the source over the image's own copy so `--reload`
means something in a detached local stack, and mounts the Playwright report
out to the host. Under act_runner the daemon is a sibling of the job rather
than its host: it resolves those paths against its own filesystem, finds
nothing, and mounts empty directories. So the backend reported "Path does not
exist fluksio/main.py" for a file the image plainly ships, and every shard
uploaded nothing — "No files were found with the provided path:
frontend/blob-report".

compose.ci.yml now puts backend's volumes back to what compose.yml declares
and drops Playwright's entirely; the shard copies its report out of the
container before the teardown instead.
