refactor(remote): remove legacy single-remote storage in favor of remotes table

Drops the per-profile remote_storage column and all legacy FTP/SFTP/S3/
Google Drive credential columns. Remote destinations are now sourced
exclusively from #__mokosuitebackup_remotes (multi-remote), which is
created at install time — so the backward-compat fallback branches in
BackupEngine, SteppedBackupEngine and loadRemoteDestinations are removed.

- sql: drop 26 legacy columns (install.mysql.sql + 02.52.25.sql migration)
- forms/profile.xml: remove legacy remote fields and ftp/gdrive/s3 fieldsets
- tmpl/profile/edit.php: drop legacy UI, add save-first prompt, use
  getOrCreateInstance for the modal, read item.params (was item.config)
- PreflightCheck: validate credentials from the remotes table; curl
  warning now applies to ntfy only
- SteppedSession: drop remoteStorage property
- language: add backup-record delete-count strings
- script.php: simplify postflight license-key prompt
