* test(logging): align DB metrics event_metadata assertions with safe redaction
PR #28909 hardened log_db_metrics to emit a minimal, non-sensitive
event_metadata (only table_name when present, otherwise None) instead of
dumping function_name, function_kwargs, and function_args onto the span. The
test in test_log_db_redis_services was not updated and still asserted
"function_name" in event_metadata, which raised TypeError (argument of type
'NoneType' is not iterable) and turned the logging_testing CI job red on
litellm_internal_staging.
Update test_log_db_metrics_success to assert event_metadata is None when no
table_name is passed, and add test_log_db_metrics_event_metadata_is_safe as a
regression guard verifying that only the table name surfaces and that sensitive
kwargs (tokens, prisma client) are never dumped.
* test(bedrock): self-heal opus-4-7 grid cells when unentitled on CI
The bedrock-claude-opus-4-7 converse cells are unentitled on the Bedrock CI
account, so they were marked xfail. xfail keeps reporting them as expected
failures even after access is granted, so the wire translation never gets
verified again. Now the cell makes the call and skips only when Bedrock
replies "is not available for this account"; the moment the model is
entitled the same cells run their full assertions with no edit.
A focused unit test pins the tolerance predicate so any other failure still
surfaces loudly and the available path still runs the assertions.
