Quotes (#583):
- Add requires_approval, approval_level, and can_be_sent; wire create form
- Migrations 145 (approval columns) and 146 (quote_items.position)
- Order Quote.items by position; set positions on create/edit/duplicate/API
- Fix view template approval branch (not_required); add web regression test
Invoices / PEPPOL:
- Use the same Factur-X embed and PDF/A-3 normalization for export and
email attachments; Associated File Data + text/xml metadata
- CII/UBL validators, pdfa3, zugferd, and invoice_pdf_postprocess helper
- Bundle compact sRGB ICC (app/resources/icc/); INVOICE_SRGB_ICC_PATH override
- Package data in setup.py; extend PEPPOL_EINVOICING.md and tests
Switch embedded invoice PDFs to Factur-X CII payloads and tighten the PDF/A-3 and AS4 handling so exports better match the standards they advertise. Document the experimental native Peppol transport path and cover the new validation and embedding behavior with focused tests.
Implement native PEPPOL transport plumbing (identifier validation, SMP/SML discovery, and AS4 send path) and make ZUGFeRD/PDF export fail fast when embedding or PDF/A-3 normalization fails. Add settings, migrations, validators, tests, and docs so compliance issues are visible and verifiable.
