/*
EVERY ADMIN ACTION EMITS AdminAction, with the signer and the call.

There was no event anywhere in this realm, so a stolen admin key's
treasury change, rate change or deletion was invisible until its effects
showed up somewhere else (audit M-4/M-6). The vault now says what changed
(nsdata/events.gno); this says who asked, through which call, with which
arguments — the line a monitor alerts on. A failed call emits nothing:
an aborted transaction keeps no events.

One event type, "AdminAction", with "fn" naming the call, so a monitor
subscribes once and a new admin call is covered without anybody updating
a list. Profile values replayed by a restore are not repeated here, only
their keys, for the reason given in nsdata/events.gno.
