Summary

Added automated invoice email delivery to customers when freight orders are delivered.

InvoiceController: POST /api/v1/invoices/{orderId}/send endpoint
InvoiceEmailService: Sends invoice PDF to customer email (validates DELIVERED status)
SmtpEmailService: Added sendEmailWithAttachment() for PDF attachments
InvoiceEmailServiceTest: Comprehensive unit tests for happy path and error cases
Made SmtpEmailService conditional on JavaMailSender bean presence
Added NoOpEmailService as fallback for test environments

All unit tests pass
Manual testing verified with MailHog - emails received with PDF attachments correctly
