Socks proxy authentication is not implemented

Duplicate Check

• I confirm I searched for existing reports and found no duplicates.

Describe the Bug

Socks requires its own authenticator, otherwise it defaults to using default credentials user=root;pass={empty}.

Sample implementation:

import java.net.Authenticator
import java.net.PasswordAuthentication

private fun configureSocksProxyAuth(
    proxyConfig: ProxyConfig
) {
    val auth = proxyConfig.auth
    if (auth !is ProxyAuth.Basic) return

    val username = auth.username
    val passwordChars = (auth.password ?: "").toCharArray() // username-only if null

    // WARNING: global for the whole JVM/app process
    Authenticator.setDefault(object : Authenticator() {
        override fun getPasswordAuthentication(): PasswordAuthentication? {
            if (requestorType == RequestorType.PROXY &&
                requestingHost.equals(proxyConfig.host, ignoreCase = true) &&
                requestingPort == proxyConfig.port
            ) {
                return PasswordAuthentication(username, passwordChars)
            }
            return null
        }
    })
}

Steps to Reproduce

1. Set socks proxy credentials in the settings
2. Restart app
3. Observe in the socks server logs that SimpMusic is trying to authenticate using default user=root; pass={empty} credentials, not the ones set in the settings

Expected Behavior

SimpMusic authenticates to the socks proxy server using set credentials

Start by locating the SOCKS proxy configuration and authentication entry point used by the settings flow. Reproduce the issue with credentials configured and check the SOCKS server logs. Done means the configured username and password are used instead of the default root and empty credentials.
