hailin d051178801 fix(electron): add gRPC connection check before subscribing to messages
The app was crashing with "CANCELLED: Cancelled on client" error when
opening the app a second time. This happened because:

1. When window was reopened, old gRPC streams were in cancelled state
2. prepareForSign/prepareForKeygen tried to subscribe on cancelled streams
3. The error was unhandled and crashed the app

Changes:
- Add isConnected() check in prepareForSign() and prepareForKeygen()
- Throw meaningful error when gRPC client is not connected
- Wrap all prepareFor* calls in try-catch in main.ts
- Return user-friendly error message instead of crashing
