fix(ui): restore effect detail scrolling

Reflow selected Helpful/Harmful spell descriptions through the retained retail text shaper, bind their authored 0x10000127 information scrollbar independently from the list scrollbar, and allow display-only text to consume wheel scrolling without becoming selectable.

Format Vitae recovery experience through retail's grouped integer presentation. Release build succeeds and all 5,832 tests pass with five intentional skips.
