SFTPGo has path confinement bypass in public browsable share partial ZIP download

Description

## Summary The public web-client endpoint for partial ZIP downloads of a browsable share did not correctly confine the client-supplied files entries to the shared directory. A requester able to reach a public share could read files located outside the shared directory, as long as the target's canonical path begins with the shared directory's name. ## Patches Fixed in v2.7.3. The fix replaces the raw prefix check with a directory-boundary–aware check.
