fix(tests): fix 7 pre-existing test failures

Menu tests (6): Tests expected merchant menu item id "loyalty-program"
but the actual definition in loyalty/definition.py uses "program".
Updated assertions to match the actual menu item IDs.

Wallet test (1): test_enrollment_succeeds_without_wallet_config didn't
mock the Google Wallet config, so is_configured returned True when
GOOGLE_ISSUER_ID is set in .env. Added @patch to mock config as
unconfigured.
