fix: wait for bunker relay connections before marking signer ready

- Decryption was hanging because relay connections weren't established
- NostrConnectSigner sends requests via relays but pool wasn't connected
- Now wait for at least one bunker relay to be connected (5s timeout)
- Prevents decrypt/sign requests from being sent to unconnected relays
- Adds detailed logging for connection status
