"""Unit test conftest — overrides session DB fixtures with no-ops.

Unit tests in this directory are pure-logic tests that do not touch the
database.  The session-scoped _db_schema fixture in the parent conftest.py
tries to connect to the test Postgres instance; override it here so unit
tests can run without a live DB.
