Login with bunker raises error if the remote signer respond with a secret in the result

[miche1e]

Describe the bug

Logging in with bunker works fine but if the remote signer put a secret instead of "ack" ui says "Unknown login error"

To Reproduce

Steps to reproduce the behavior:

1. Go to https://phoenix.social/login
2. Click on Sign in with key
3. Enter the bunker link (with a secret) and click login
4. See error

Expected behavior

I expect it to work like when the remote signer sends "ack" in the result

Desktop (please complete the following information):

• OS: nixos
• Browser: firefox, chromium
• Version: 144.0.2 (64-bit) & 142.0.7444.134 (64-bit)

Looking at the code seems that when the remote signer responds to a connect request if the result is not "ack" it raises the error. But by the nip46 specification the result may be an arbitrary secret created by the remote signer to use for all subsequent connect requests.
