Move the file descriptor and time series graphs to the bottom of the storage dashboard. These graphs are relatively niche and less useful than the other graphs within the dashboard. Epic: none Release note: none
Previously the storage dashboard had two separate graphs for log-commit latencies (p99 and p50) and two separate graphs for command-commit latencies (p99 and p50). This commit consolidates these four graphs into two: one for log-commit latencies and one for command-commit latencies. Epic: none Release note: none
Add two missing I/O write categories to the storage dashboard's 'Disk Write Breakdown' graph: pebble-manifest and pebble-blob-file-rewrite. Epic: none Release note: none
Add a new graph to the storage dashboard within the DB Console, graphing block bytes loaded by iterators per category. Epic: none Informs cockroachdb#156391. Release note: none
When focused on a single node, some DB console graphs show per-store metrics with an additional graph aggregating across the node's stores. In the common case of a single-store node, the aggregated metric and the per-store metric are the same and make the graph more difficult to parse. This commit updates these graphs to only include the aggregated metric if a node has more than one store. Epic: none Release note: none
Extend the storage dashboard to include value separation metrics. For now this includes referenced and unreferenced value byte totals and the sum of the size of all blob files. Informs cockroachdb#156391. Epic: none Release note: none

Rework the storage dashboard within the DB console to consolidate some graphs and extend the dashboard with additional observability introduced in recent releases.
