fix: keep playwright install stderr for debugging

Playwright install stderr is diagnostic signal — version/network errors,
missing system libs, or browser download failures all surface here. Only
suppress stderr on the noisy npm install step. Also pin the image-tag /
client-version relationship with a code comment on one compose file so
future bumps know to keep them aligned.
