test(04-06): add failing RED tests for LIST-04 SSE fan-out + bounded backoff

- API: 5 failing fan-out spy tests (subscribeListEvents receives 0 events since publishListEvent seams commented out in lists.ts)
- API: 4 D-04 scoped subscription tests (green — listAccess primitives from 04-02 already proven)
- PWA: useListSSE.test.ts — all 7 tests fail (module-not-found; hook not yet created)
- Covers: item:added/updated/deleted, list:updated/deleted fan-out + D-11 bounded backoff exhaustion + D-10 reconnect invalidation

// ---------------------------------------------------------------------------
// LIST-04: SSE fan-out assertions — GET /api/sse/lists + publishListEvent triggers
//
// Security focus:
// - T-04-02 (D-04): private list events MUST NOT be delivered to a member who
// is not the owner — confirmed at the route/subscription layer.
// - T-04-01: unauthenticated requests → 401
//
// These tests assert the route-layer behavior by:
// 1. Spying on publishListEvent to confirm it fires after each write mutation.
// 2. Testing that GET /api/sse/lists returns 401 when unauthenticated.
// 3. Testing D-04: GET /api/sse/lists for user B does NOT subscribe to channels
// for user A's private list (verified via accessible-list gating).
