Returns audit records for the authenticated user's tenant, ordered latest
to oldest, with optional filters for audit domains, actor IDs, and a
Unix-timestamp time range. Uses cursor-based pagination.

Tenant is derived from the user token — do not pass tenant as a path or
query parameter.

Pagination: When continuationToken is non-null in the response,
post the same request body with pagination.continuationToken set to
the returned value to fetch the next page. The nextPageLink field
provides the full endpoint URL for convenience.

Rate limit: Tier 2 (60 requests/minute per tenant).
