fix: switch to python:3.11-slim-bookworm base image

The tiangolo/uvicorn-gunicorn-fastapi image moved to Debian Trixie
(testing) which Playwright doesn't support — install-deps fails on
renamed font packages. The tiangolo image only adds uvicorn/gunicorn
which are already in requirements.txt, so switch to the official Python
slim-bookworm image directly. Also removes the old commented-out Chrome
manual install block that hasn't been used since the Playwright migration.
