Install Python 3.12 + uv on Playwright Noble base image

The Playwright image ships Ubuntu 24.04 + Chromium but no Python.
This commit adds:
- Ubuntu apt mirror (tuna) since ubuntu.com repos are blocked from Iran
- python3 + python3-venv via apt
- uv via curl installer
- uv sync for project deps (targets Python 3.12)

Admin stage stays on python:3.11-slim (no Chrome needed).
