Resolve the FTP Password from OS Secure Storage

Demonstrates the EnableSecrets property, which lets password properties contain a secret specification beginning with !! that Chilkat resolves from the operating system's secure storage instead of using the literal text.

Background: This is a cleaner alternative to reading a secret yourself and assigning it: with EnableSecrets on, you set the password to a reference like !!my_secret_name and Chilkat fetches the real value from the platform's secure store. The literal password never appears in your source or configuration, which is exactly the practice recommended throughout these examples.
