fix(fdc): Skip integration tests when DATA_CONNECT_EMULATOR_HOST is not set

Added a check_emulator autouse module fixture in integration/test_data_connect.py.

Unlike services with dynamic resource creation (e.g., Realtime Database), Data Connect requires a pre-deployed Cloud SQL Postgres schema and connector. Since live integration projects do not host these resources, Data Connect integration tests are strictly emulator-only and are safely skipped when DATA_CONNECT_EMULATOR_HOST is absent.
