conftest.py

"""Root conftest.py — pre-imports app_main with create_tables patched to a no-op.

app_main.py calls create_tables() at module level which connects to Postgres.
By patching Base.metadata.create_all before the first import we keep the test
session entirely in SQLite (managed by tests/conftest.py fixtures).

Sets ENV=test so CeleryBackend is not activated during tests.
