fix(admin): drop whitespace-nowrap on api-tokens date cells (5th attempt)

The /admin/api-tokens page has been painting a residual horizontal
scrollbar for four releases despite column-hide, mobile card-list, and
the admin section-strip `no-scrollbar` fixes. A fresh production probe
confirmed the actual culprit: the "Last used" and "Created" `<td>`s
carry `whitespace-nowrap`, and `formatDateTime` renders strings like
"05.05.2026, 21:46" (~110px) that exceed the 12% colgroup allotment
(~84px on a 700px content area). `whitespace-nowrap` wins over
`table-fixed`'s width contract, so the table's intrinsic width exceeds
100% and the wrapping `overflow-x-auto` paints the scrollbar.

Dropping the two `whitespace-nowrap` classes lets the date+time wrap
to two lines on narrow viewports. The card grows by one row but no
scrollbar — and at >1024px desktop the unwrapped string already fits
in the 12% allotment so the visual is unchanged for the common case.

Picked option 1 of the three W1a probe found (drop nowrap, switch to
formatDateShort, or hide "Created" at md): smallest two-line diff, no
i18n surface impact, no information loss.
