test(gateway): pin DEFAULT_DB_PATH in fixtures to prevent real state.db writes

Fixtures that instantiate SessionStore() trigger SessionDB() with no args,
which resolves to ~/.hermes/state.db via the DEFAULT_DB_PATH module constant
(snapshot of get_hermes_home() at hermes_state import time).

The autouse _hermetic_environment fixture in tests/conftest.py monkeypatches
HERMES_HOME env, but DEFAULT_DB_PATH is already cached by then. Per-test
monkeypatch.setattr(hermes_state, 'DEFAULT_DB_PATH', tmp_path/'state.db')
forces the DB into tmp_path so the tests can't leak into the real profile.

Verified by counting u1-prefixed sessions in real state.db before/after:
delta=0.
