- New groupMembership.findMany query, tenant-scoped via group.tenantId
(GroupMembership has no own tenantId column)
- Response shape changes from an array to { groups, modules }; modules
entries stay field-identical to before
- Group without any module grant now stays visible, closing the
reproduced defect
- GET /module-grants/matrix, GET /module-grants/users/:userId,
POST /module-grants, DELETE /module-grants — alle vier rollengeschützt
(RolesGuard + Roles ADMIN/SUPER_ADMIN)
- matrix vor users/:userId deklariert (Beschattungsfehler-Vermeidung)
- GroupsModule bindet ModuleGrantsController/-Service ein; kein Import
von ModuleRegistryModule nötig, da der Service nur PrismaService braucht
