App streaming pipeline, dashboard server status, account enable/disable, game-linked plans

- Add C++ native streaming engine (RTMP client, EGL context, streaming engine, JNI bridge)
- Add pre-built arm64-v8a libs (librtmp, libssl, libcrypto, libz) and headers
- Add Kotlin streaming layer (NativeStreamingEngine, StreamingManager, StreamingStats)
- Add AIDL streaming interface (ILckStreamingService, ILckStreamingCallback, StreamingConfig)
- Add LckStreamingServiceImpl with BIND_STREAMING action support
- Add APP_STREAMING execution mode with auto-start/stop on plan lifecycle
- SDK: add bindStreaming(), submitVideoFrame(), submitAudioFrame() to LckControlClient
- Dashboard: replace linked accounts with server status card, move health polling from nav
- Remove health check dot overlay from Dashboard nav icon
- Accounts: add enable/disable toggle per account (persists locally, excluded from default plans)
- Plans: add gameId field linked to game package ID, resolved from ClientTracker for default plans
- Service: pass executionMode+gameId through createStreamPlan, filter enabled accounts in createDefaultPlan
- Room DB migration 4→5: add isEnabled column to linked_accounts, gameId column to stream_plans
- Add docs (hub vs control comparison)
