jbot: disable local memory in Hermes Agent mode

In Hermes mode JBOT is a pure voice UI — memory is owned by the Agent:
- Backend: sys prompt excludes local memories when backend_mode=hermes
- Backend: config_view now returns backendMode so the frontend can adapt
- Frontend: App.jsx loads backendMode on mount via apiConfig()
- Frontend: memories not passed to apiChat() when isHermesMode
- Frontend: memory extraction (apiExtractMemory) skipped when isHermesMode
- Frontend: MemoryPanel hidden in Hermes mode; replaced by subtle
