PDF invoice reports + SMTP email sending
PDF Reports: - Professional invoice HTML renderer (company header, partner address, styled line items, totals, Odoo-purple branding, A4 @page CSS) - wkhtmltopdf installed in Docker runtime stage for real PDF generation - Print button on invoice form (opens PDF in new tab) - Exported HtmlToPDF/RenderInvoiceHTML for cross-package use SMTP Email: - SendEmail + SendEmailWithAttachments with MIME multipart support - Base64 file attachments - Config via ODOO_SMTP_HOST/PORT/USER/PASSWORD/FROM env vars - LoadSMTPConfig helper, nil auth for relay servers Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
