Add PUT /admin/api/groups/:id/rename (owner role) which re-points the group's routes, migrates the per-group webhook secret (tenant:{id}) and pending invites, and records an audit entry. The group editor's id field is now editable and the console renames first, then persists remaining edits under the new id.
- New MembersPanel: role switching, add/remove members, invite-link
generation with copy/revoke, pending invite list
- New Audit tab (AuditLog.vue) with group filter
- Role-aware UI: viewer hides route/group edit actions (RouteCard readonly),
owner-only controls, role badge + member count on group cards
- GroupEditor: members managed via panel, owners field super-admin only
- en/zh i18n and CSS for the new panels
Add a super-admin-only Groups tab to create, edit and delete groups
(name, admin ids, owner scope). Routes now require a group via a select
in the editor, group names are shown on route cards, and the new
useMe/useGroups composables back the UI.
