v2.5.3

Added

• Radarr, Sonarr, Lidarr, Whisparr and Prowlarr can be backed up with Authentication Required set to Enabled: when Test connection finds the app asks for a login, the card shows Username and Password, and Backuparr signs in (Forms or Basic, detected by itself) only to download the backup. Prowlarr discovery uses Prowlarr's login too. A backup that starts needing a login says so in its error and notification.
