[Discover][APM] Enable the traces doc viewer by index and data_stream.type

[iblancof]

Summary

The span and transaction document profiles are enabled by checking the document’s data_streams.type and verifying if it's set to traces.

We would like to improve this by filtering if the document index matches the configured APM indexes for traces.

Note

To enable index-based functionality, we first need to complete #211414, which will establish how to retrieve APM indexes from the configuration.

Acceptance criteria

	Description
AC1	The new overview tab will be enabled if the document data_stream.type is traces OR if the _index is part of the spans/transactions APM index patterns. (⚠️ As mentioned above, the index requirement is currently blocked by another issue)
