Toggle VESTS / HP in account mini-balance chart per setting

It would be useful to be able to switch VESTS to HP and vice versa in the mini-balance chart displayed on the user's profile. The switch would happen in alignment with the setting VESTS/HP. Would also be useful to add a toggle in the box that auto-defaults to setting, and can be overridden by the user, as is the case elsewhere.

If the performance is NOT acceptable to convert values on the fly, we could discuss an API level change to support receiving HP alongside VESTS.
