Show initial estimates instead of detailed estimates in the capacity report

Currently you can set an initial estimate, and later on add a detailed estimate.

Since it is usually more accurate, the capacity report will use a detailed estimate, if it is available, to visualize a team's capacity.

However, there is a reporting need to see what the initial estimates are without seeing detailed estimates.

It would be helpful to add a configurable option to view initial only, detailed only, or best estimate.
