The ephemeral cache creation breakdown fields (ephemeral_5m_input_tokens, ephemeral_1h_input_tokens) were being recorded as metrics, which required adding them to the standard metrics allowlists. Move them to span metadata instead, since they are informational breakdowns of the already-tracked prompt_cache_creation_tokens metric. This fixes the CI failure in test_standard_metrics_crawl where the integration tests reject unrecognized standard metric names.

The ephemeral cache creation breakdown fields
(ephemeral_5m_input_tokens, ephemeral_1h_input_tokens) were being
recorded as metrics, which required adding them to the standard
metrics allowlists. Move them to span metadata instead, since they
are informational breakdowns of the already-tracked
prompt_cache_creation_tokens metric.
