ci(test): replace alembic with Base.metadata.create_all (matches cueapi-core conftest)

First push failed because OSS migration set ends at 023 while the User
model declares an `api_key_encrypted` column with no migration backing it.
That's a parity drift in cueapi-core (private migration 019 in the hosted
repo includes the column; the OSS port renamed/replaced it with the
alert-webhook bits but kept the column on the model). `alembic upgrade
head` produced a schema missing that column → register endpoint 500'd
on the User SELECT.

Switch the CI bootstrap to model-driven schema init via
`Base.metadata.create_all`, which is the exact pattern cueapi-core's own
`tests/conftest.py` uses (and which is robust to model/migration drift
because the model is the source of truth for tests).

Imports the same model list as conftest so all tables register before
create_all runs.
