CHEF-33431: detect platform-ui image dynamically after build-docker.sh

Replace hardcoded IMAGES="platform-ui:local" with the same dynamic
grep used by Strategy 1 — detects whatever tag build-docker.sh actually
produced. This decouples the workflow from the script's tag name and
works correctly regardless of branch, PR, push to main, or release.
