- EmailService: add RedirectIfNonProd() mirroring SmsService pattern;
reads SendGrid:DevRedirectEmail and redirects all outbound email in
non-production so real customers are never contacted on local/dev
- appsettings.json: set DevRedirectEmail to spouliot@scppowdercoating.com
- PdfService: revert Opacity() (not in QuestPDF 2024.12.3); use
Colors.Green.Lighten2 for stamp + border to achieve lighter look
