Sync the permission CRUD overhaul from the internal CLI (MR 28965577):
- drive/doc permission list and wiki member list now accept --next-token
to follow the server cursor (totalCount/hasMore/nextToken); --limit maps
to pageSize capped at 50 instead of the rejected maxResults=200 path
(fixes#1065)
- permission add/update/remove and wiki member add/update/remove accept a
--members JSON array (USER/DEPT/CONVERSATION/TAG grantee types, each with
its own roleId) with optional --notify; legacy --users/--role stays
- cursor/page-token hidden cross-product aliases now resolve to next-token
- regenerate param_aliases_generated.go; wiki member list override no
longer blocks cursor
- update mono/multi skill references and add change fragment
