Add Dockerfile for the app

python:3.12-slim, installs the package (pip install .), runs pending
Alembic migrations before starting uvicorn. Migrations/alembic.ini/
scripts are copied in as-is (not part of the installed package) since
alembic and generate_master_key.py run directly against the source
tree.
