FileRise: ZIP extraction writes blocked file extensions to disk, bypassing the upload blocklist

Description

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.16.0, FileRise archive extraction does not apply UploadNamePolicy::isAllowedForWrite() before ZipArchive::extractTo() writes entries into the destination directory. An authenticated user with upload and extract permissions can place a blocked extension such as a PHP-family file inside a ZIP and cause it to be written to disk even when normal uploads reject that filename. Post-extraction metadata pruning does not remove the blocked file, so deployments that execute uploaded content may permit code execution. This issue is fixed in version 3.16.0.
