This pull request addresses an issue with metric reporting by correcting the names of internal channels used for Prometheus metrics. This ensures that the system accurately monitors and reports buffer usage for the correct channels, improving the reliability of observability.
Highlights
- Metric Channel Name Correction: Corrected the channelNames array in block/metrics.go to accurately reflect the channel names used for Prometheus metrics, specifically replacing "header_in" and "data_in" with "height_in".

Code Review
This pull request corrects the channel names used for metrics in PrometheusMetrics to align with recent changes in event handling. The channel names header_in and data_in are replaced by height_in, which is consistent with the NopMetrics implementation and the usage of heightInCh. While the change itself is correct, the associated tests in block/metrics_test.go were not updated, which will lead to build failures. It's critical to update the tests to reflect these new metric names.
