Converted all notification emails to the branded layout by routing them through a shared Blade template and swapping

the MailMessage builders to use view(). This keeps the existing copy/labels but aligns the look with resources/views/
  emails/partials/layout.blade.php. I also switched the customer add‑on receipt notification to reuse the existing
  branded view and added missing translations for the upload pipeline alert.
