Use Playwright base image for worker services

Replace chromium/chromedriver apt installs with
mcr.microsoft.com/playwright:v1.62.0-noble for worker containers.
Admin service stays on python:3.11-slim since it doesn't need Chrome.

This removes the build-time patch_driver.py step since Playwright ships
with a pre-patched Chromium binary. Also split docker-compose into
separate images (seed-admin / seed-worker) with explicit build targets.
