trpc-protected-procedure-is-not-authorization

In the TaskFlow codebase, protectedProcedure only verified authentication (JWT present) but did not enforce ownership or role-based access. Any authenticated user could call tasks.updateStatus or taskUpdates.create on any task they didn’t own. Role fields (admin/member) existed in the schema but were never checked in router middleware. Row-level authorization must be added per-procedure, not just at the authentication layer.
