📄 Description

The add_file_context function used a positional zip() to pair API payload messages with DB-stored messages. After
process_messages_with_output() expands assistant messages containing tool calls into multiple OpenAI-format messages (assistant + tool results), the payload list becomes longer than the stored list. This caused the zip to misalign, so subsequent user messages never received their attached_files tags -- the model could see uploaded images via vision but had no file URL to pass to edit_image.

Fix: filter both lists to user-role messages only before zipping. User messages maintain the same order in both lists regardless of assistant message expansion, restoring correct file context injection.

Fixes #21878
