Show claude extras in main panel

[matheusfillipe]

Problem

There is no configuration of which usages to show in the main panel. I would like to see extra credits usage. They already show in claude tab.

Proposed Solution

Either show it by default or make it configurable.

This was by design due to how plugins expose data, but I think being able to "pin" metrics is a good idea.
