fix(activity): a run's quota reads with its unit, its outcome keeps room at a large text size, a token's audit rows read in Hungarian

The run list showed the quota spend as a bare figure and, at the largest text size on a 1024-wide
screen, its fixed columns left the outcome column no width at all. The outcome now keeps 10rem and
the trigger column gives way; the audit list's summary keeps the same floor. A run that stored no
log line says so instead of linking to an empty list. An API token revoke and a token's file work
rendered the server's English line under the Hungarian UI; both are rebuilt in the reader's
language, and the test holds the server's wording.
