[DO] Address review feedback on metrics filter changelog (#31441)

* [DO] Address review feedback on metrics filter changelog

- Move the dashboard screenshot to immediately after the DashButton so
  readers see the UI before the description of how to use it.
- Note that the autocomplete only lists objects with invocations during
  the selected time range, so a missing object means no recent
  invocations rather than deletion.

Addresses post-merge review comments on #31316.

* [DO] Replace em dash with two sentences in metrics changelog

+Start typing an ID or name into the filter and select a match from the autocomplete dropdown. The autocomplete only shows objects with invocations during the selected time range, so an object that does not appear has not been invoked in that window. This does not necessarily mean the object has been deleted. Every chart on the page updates to reflect only the selected object. This makes it easier to identify and investigate a single Durable Object when debugging a high-traffic object, an error spike, or unexpected storage usage. Clear the filter to return to namespace-level metrics.
 
 Metrics are powered by the [GraphQL Analytics API](/analytics/graphql-api/), so standard analytics behavior such as ingestion delay and [sampling](/analytics/faq/graphql-api-inconsistent-results/) applies.
