v4.928.1.5.120 — delivered guard last-action invoice evidence

Hotfix for reconstructed opportunities where the detail page shows a completed SEND_INVOICE state but the delivered workflow guard cannot find the legacy task through tasks.opportunity_id.

Changes:

• workflow_guard.get_workflow_context() now selects last_action_code and last_task_id.
• Invoice task lookup also checks opportunities.last_task_id.
• Adds a conservative fallback: last_action_code=SEND_INVOICE counts as invoice-sent evidence only when an invoice exists and no pending invoice-send task contradicts it.
• Exposes invoice_sent_last_action_evidence in the workflow context for debugging.
