Wolfpup Progress UI - Paw QoL

In this image, I only have 1/5 Curiosity, but due to the progress sharing the same UI as the unlock, it looks like 2/5.

Could the Paw icons be separated into two parts - a core, and an outline - and work like this:

- As the 'training' progresses, the outline will fill up either from left to right or from bottom to top
- The Core will remain hollow, until the point is actually specced

This will work well I think both for the current implementation, and even better for the eventual manual speccing that DE are planning to implement soon!
