Strip Path Info from Attachment Filenames

Demonstrates the Chilkat Email.RemoveAttachmentPaths method, which removes relative or absolute path information from the attachment filenames stored in the MIME, leaving only each final filename component. This example adds an attachment whose name includes a path and shows the filename before and after.

Background: An attachment filename that carries a path (like reports/2026/q3/summary.txt) is a problem: some mail clients display the whole path, and — more seriously — a path with .. segments can be a directory-traversal risk when attachments are saved to disk. Reducing every filename to just its final component (summary.txt) makes the message cleaner and safer to handle.
