/**
 * Backup credential exposure regression tests.
 *
 * The generic settings reads (GET /admin/settings, GET /admin/settings/:type)
 * masked the recaptcha/umami/rybbit keys but returned backup_s3_secret_key
 * and backup_rsync_ssh_key (an SSH PRIVATE KEY) in plaintext to any
 * settings.view holder; GET /admin/backup/config returned them too. Both now
 * mask, and PUT /admin/backup/config skips the mask sentinel so the edit
 * form round-trips without clobbering stored credentials.
