fixes #8491: add vars for table padding
fixes #8477: use var for rounded image border-radius
Drop `.nav-header` for `.dropdown-header`

* Since we no longer have `.nav-list`, I've nuked the `.nav-header`
* However, dropdowns can still have section headings, so I've kept that
around with the addition of `.dropdown-header`
* Restyled it a smidge as well
Bump tooltips to use `@font-size-small` (11px to 12px)
Fixes #8441: remove `@font-size-mini`
Fixes #8452: adds `.active` to table classes
