Check FTP Connection and Login Status

Demonstrates the connection-status properties ConnectVerified, LoginVerified, ConnectFailReason, and Greeting.

Background: When Connect fails, these properties separate the possible causes: ConnectVerified shows whether the TCP connection was established at all, LoginVerified whether authentication then succeeded, and ConnectFailReason gives a numeric code pinpointing the failure — far more actionable than a generic error for distinguishing, say, an unreachable host from a bad password. The Greeting captures the server's opening banner, sometimes useful for identifying the server or its policies.
