10EVERY ADMIN ACTION EMITS AdminAction, with the signer and the call.
11
12There was no event anywhere in this realm, so a stolen admin key's
13treasury change, rate change or deletion was invisible until its effects
14showed up somewhere else (audit M-4/M-6). The vault now says what changed
15(nsdata/events.gno); this says who asked, through which call, with which
16arguments — the line a monitor alerts on. A failed call emits nothing:
17an aborted transaction keeps no events.
18
19One event type, "AdminAction", with "fn" naming the call, so a monitor
20subscribes once and a new admin call is covered without anybody updating
21a list. Profile values replayed by a restore are not repeated here, only
22their keys, for the reason given in nsdata/events.gno.
