When the runner job runs inside a container, compose's relative
`./playwright/playwright-report` resolves to a path that exists
only inside the runner container, so the host's docker daemon
silently bind-mounts an empty dir and the report never lands
anywhere we can read.
Drop the bind mounts; keep the playwright container around
(--name e2e-pw, no --rm); after the test, `docker cp` the
report and traces out into the runner's workspace volume so
upload-artifact has something real to upload. The new test-results
directory (Playwright traces, screenshots, videos) is also
included so failure post-mortem doesn't need a re-run.
