# v4928.1.5.39 — Odoo panel import + draft attachment selection hotfix

Hotfix read/write behavior unchanged except for draft/document selection persistence.

## Fixes

- Fixes opportunity Odoo panel error `name 'engine' is not defined` by importing DB engine/text explicitly.
- Fixes SEND_PROFORMA draft revision/send validation where older persisted drafts showed an ORC selected in compact UI but posted no `selected_document_ids`.
- Centralizes effective selected-document fallback in task UI endpoints so generate/save/revise/send use the same ORC/invoice default.
- Keeps ClientFlow business rule: proforma = Jasmin ORC.* quotation document.

## Validation

- `python -m compileall -q app scripts tests`
- targeted import smoke tests
