fix(admin): render token-name timestamps in Berlin time

The auto-issued token-name viewer rebuilt the dd.MM.yyyy HH:mm suffix
from `Date.getUTC*` accessors, producing 19:46 instead of the 21:46 a
Berlin-time admin would expect for a token issued at 19:46 UTC. Route
the parsed Date through `Intl.DateTimeFormat("de-DE", { timeZone:
"Europe/Berlin", … })` so the embedded timestamp matches every other
display surface in the app.
