Move appendWsUrls out of the class as a public function, and modify the function references in test.ts.

Move appendWsUrls out of FailoverProxy class and export as an independent function. **Rationale:** Code simplification - the function does not depend on any internal state of FailoverProxy Make the function reusable outside FailoverProxy scope, especially in the new node selection (ping) feature **Regarding function location:** Although the function is separated from the class, keeping it in failoverProxy.ts is reasonable because: The function was originally designed to handle proxy URLs and is closely tied to the Endpoint interface, which is still defined in failoverProxy.ts **Note: **The function is only used in tests, not found in other directories, so only need to adjust the import in test.ts.
