Backup bows out of the phone — the zipped-share future replaces it, later

IndieBackup comes out whole: the package, the Backup directory, the Settings section, the .kanbanbackup document type and its onOpenURL restore path. Settings is now the About section alone. The Files-app keys stay — they serve local-board visibility, not backups. Board sharing as a zipped archive is the planned replacement and is deliberately not started here.
