Subject: [PATCH] feat(real-estate): expose GET /real-estate/log observability
 endpoint

- main.py: add GET /real-estate/log endpoint (feature-flag gated).
  Returns total_invocations, success_count, failure_count, and
  last 50 log entries from real_estate._invocation_log.
  Returns 404 when ENABLE_REAL_ESTATE is not true.
