### What's Wrong?

I Tried to connect to the dataverse mcp server, provided the wrong client id, there is no ability to fix it, stuck in a loop of endless auth redirects.

### What Should Happen?

add a delete button

### Error Messages/Logs

```shell

```

### Steps to Reproduce

Create a dataverse mcp connection, provide the wrong client id
connection fails, shows reconnect button, reconnect fails, no ability to reenter credentials. This is especially bad with dataverse because I need to add it once per environment, this doesn't work either

### Additional Information

_No response_

Start at the macOS app's Settings → Connectors flow and reproduce the failed Dataverse MCP connection with an invalid client ID. Trace the reconnect state and verify that a delete action removes the saved connection or credentials, allowing credentials to be entered again for each environment.
