fix header design

[negue]

Requested Changes

• Health, Experience, and Mana bars should have a border-radius of 1px
• Fix placement of Health, Experience, and Mana bar tooltips (2px under the bar)

In order to change the tooltip position, its only possible to change by the tooltip-class (no ability to add a custom class)

I extracted the progress and tooltip to a custom component, which then could be styled within the container

looks like there's a minor problem here with the tooltips appearing under the header

thanks for catching that one, it was a scss-scope issue
