fix(FN-2024): gate task SSE subscriptions by active view
- Add an sseEnabled option to useTasks and skip SSE subscription setup when disabled - Compute taskSseEnabled in App based on board/list views and pass it through to useTasks - Migrate useRemoteNodeEvents from raw EventSource management to shared subscribeSse bus usage - Update App, useTasks, and useRemoteNodeEvents tests to cover SSE gating and bus-based event wiring
