fix(desktop): Desktop app fails to connect to authenticated remote server on startup #16123

Description

When a remote server requiring authentication (username/password) is set as the default server, the desktop app fails to connect on startup with an error message.

The root cause is in packages/desktop-electron/src/main/index.ts, where the setupServerConnection() function calls checkHealthOrAskRetry(customUrl) without passing credentials. The checkHealth() function supports a password parameter, but it's not being used during the startup health check.

This is related to #16096, which has a similar issue in the CLI run --attach command path.
