Nerd stats open with a tap

On a touch screen a nerd-stats tooltip showed only through the browser faking hover, unreliably, and couldn't be
scrolled. Where the pointer can't hover (AppStatusService.CanHover), a tap on a NerdTip now opens its rows in a sheet
from the bottom; the trigger is focusable, says it opens a dialog, and is at least 44px on touch. A closed tooltip takes
no room any more (daisyUI only made it transparent, and one past a card's edge made a phone's feed scroll sideways),
and on touch it never shows. The rows are a component of their own (NerdRows), at 12px on phones. A card's More menu
has a Details entry on phones that gathers the post's, its author's, its place's or CDN's and its counts' rows in one
sheet. A picture's tip doesn't open on a tap, the picture does.
