feat: align metrics title to the right

[ktmud]

🏆 Enhancements

Align table headers for numeric metrics to the right, just like metric values themselves. Fixes #714.

This isn't necessarily the behavior all users want, but is the recommendations of many design guidelines. The plan is to provide a way for users to customize this in the future.
