fix: add loop_scope="session" to integration tests to fix AsyncMongoClient event loop error

Add loop_scope="session" to all test decorators in test_trigger_deduplication.py
to ensure tests run in the same event loop as the session-scoped app_started
fixture. This fixes "Cannot use AsyncMongoClient in different event loop" errors.
