Add libpq-dev for psycopg2-binary Python 3.14 builds
Summary
psycopg2-binary doesn't have pre-built wheels for Python 3.14 yet, so it needs to build from source. This requires PostgreSQL development headers (libpq-dev) to be present in the CI base image.
This fixes Python 3.14 CI for all HAF-based repos that use psycopg2-binary (HAfAH, hivemind, etc.).
