Sidebar entries Backup and File Disk now read Backups and File Disks to match how the underlying pages actually behave (each one lists/manages multiple entries) and to align with the recently added Font Packages entry. The settings.{backup,disk}.title pluralization slots are collapsed to plural-only so the existing $t(..., 1) call sites in AdminBackupView, AdminFileDiskView and the legacy v1 BackupSetting view render the plural form on the page header without touching any Vue code.
Also finishes the Fonts → Font Packages rename: menu_title.fonts and fonts.title both read Font Packages, and fonts.description leads with 'used exclusively when generating PDF documents' so the PDF-only scope is unmissable.
