Handle transient 503 errors in MCP registry live test

[Copilot]

Integration test TestMCPRegistryClient_LiveGetServer was failing when the MCP registry returned 503 errors for specific servers, despite those servers appearing in search results. The test assumed all searched servers are always retrievable.

Changes

• Skip test on 503 status codes and related transport errors (upstream connect error, connection refused)
• Preserves existing network/firewall restriction handling

// Now handles transient registry unavailability
if strings.Contains(err.Error(), "503") || 
   strings.Contains(err.Error(), "upstream connect error") ||
   strings.Contains(err.Error(), "connection refused") {
    t.Skipf("Skipping due to temporary registry unavailability for '%s': %v", serverName, err)
    return
}

Makes integration tests against live external services resilient to temporary availability issues.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
