pdfjs-dist resolves to 5.7.284, which requires Node >=22.13.0 || >=24.
With engine-strict=true in .npmrc, npm ci hard-fails on the Node 20 base
image, so the frontend dev server crash-loops (and a clean build fails).
CI runs the frontend on Node 22 (Playwright image), so the committed
lockfile already assumes 22. Bump all three Dockerfile stages to match.

The observability work moved actuator to a separate management port
(management.server.port: 8081), but the dev compose healthcheck still
probed :8080/actuator/health, which 404s. The backend was reported
unhealthy and the frontend (depends_on: backend healthy) never started.
docker-compose.prod.yml already uses 8081; this aligns dev with it.
