[Feature]: Allow for alternate WS Port

### Problem or use case

The WS port of 6768 conflicts with an internal OAUTH callback for one of our internal applications.

### Proposed solution

Considering

https://github.com/stablyai/orca/blob/98a78f1e0c4d40917ad3b5c7dee3e67ff2354e0f/src/main/runtime/runtime-rpc.ts#L29

allow for a configuration variable that starts up using a different port.

### Alternatives or additional context

We will likely update our tool to allow for different ports too but I suspect there might be others who could run into the same issue.
