fix: setup pool and relays BEFORE bunker reconnection subscription

- Move NostrConnectSigner.pool assignment before active account subscription
- Move pool.group(RELAYS) before subscription
- This ensures pool is ready when bunker signer tries to send requests
- The subscription can fire immediately, so pool must be configured first
- Add log to confirm pool assignment
