deps.get_current_user_from_request now stashes the decoded payload on
request.state.auth_payload so AuthMiddleware can populate the
workspace_context ContextVar without a second decode. Reset is paired
in the same try/finally as user_context to keep teardown atomic.
Also adds:
- auth.models.ActiveWorkspace — minimal proxy that satisfies the
CurrentWorkspace protocol (id + role only).
- auth.models.User.default_workspace_id — surfaces the DB column added
in T4.4 so the eventual /auth/me payload can reference it.
