Streams every event matching the same filters the list accepts, as CSV,
with the header row eventId,occurredAt,action,category,source,actorType,actorId,requestId,resourceType,resourceId,outcome,summary,changedFields.
Not pageable: an export is always the whole filtered set, newest
first, with no upper bound on rows. Columns are exactly the list's
(field names for data changes, no values); multiple changed field
names share one space-separated cell, and actorId carries no
display name.
Cells are quoted (inner quotes doubled), values starting with =,
+, -, @, a tab or a carriage return are prefixed with a visible
apostrophe so spreadsheets treat them as text, rows end CRLF, and the
response is UTF-8 with
Content-Disposition: attachment; filename="audit-events.csv".
