File rename templates & admin torrent approval

Add support for admin-driven interactive torrent selection and a file rename/template feature. Integrates an InteractiveTorrentSearchModal into the pending-approval admin UI, adds an admin approve flow that accepts an admin-selected torrent, and surfaces user/admin-selected torrent details in the UI. Introduces fileRenameEnabled and fileRenameTemplate settings (API + UI), persists them to configuration, and clears related caches. Pass renameConfig through the organize/organizeEbook flows and implement renaming in the FileOrganizer (single/multi-file handling). Enhance path-template utilities with conditional block resolution, filename-template validation, mock filename previews, and a buildRenamedFilename helper. Update tests to cover conditional templates and filename preview behavior.
