Give each xdist worker its own Postgres database and Redis logical DB so transactional tests can run concurrently. Integration tests stay serial. Co-authored-by: mike <mike@mikebian.co>

Motivation
Non-integration tests are independent enough to run in parallel, but the suite currently executes them serially.
pytest-xdistshould cut that wall-clock time, especially on CI.A previous attempt (#61) rewrote worker database URLs after
appwas imported.app.setup()already binds Postgres and Redis at import time, so every worker still shared the main test database.Integration tests stay serial: they share a live server, browser, and truncation-based DB reset.

Non-integration tests:
just py_test(xdist on). Integration tests remain a separate serial pytest invocation.Links
