fix(admin): humanise auto-issued token names in viewer

The native auto-login flow names tokens by suffixing the issuing
call's `Date.now().toISOString()`, so the admin viewer rendered
"iOS auto-login 2026-05-05T19:46:20.603Z" — readable as debug
output, not as something a person picked. Added a renderer-side
formatter that detects the trailing ISO timestamp and rewrites
the cell to "iOS auto-login · 05.05.2026 19:46". Manual token
names without an ISO suffix pass through unchanged.
