Fix async example scripts: remove deprecated method calls and close session on auth failure

- functional_testing.py: replace batch.records.get() with batch.records.retrieve();
  close client session on auth failure to avoid unclosed session warning
- sql_examples.py: remove odata_select/odata_expand/odata_bind calls (deprecated
  sync-only helpers not available on async client); keep only odata_expands()
