Description

When using openclaw message send --channel msteams --media <file> to send a file to a user, the file consent card appears in Teams but clicking "Allow" or "Decline" fails with "This card action is not supported by EVA."

Steps to Reproduce

1. Create a file in the agent workspace
2. Run: openclaw message send --channel msteams --target "conversation:<convId>" --message "Here is a file" --media /home/node/.openclaw/workspace/test.csv
3. Teams shows a consent card: "EVA needs permission to upload this file to your OneDrive"
4. Click "Allow"
5. Error: "This card action is not supported by EVA"

Expected Behavior

Clicking "Allow" should upload the file to the user OneDrive and show a file card with download link.

Actual Behavior

The consent card appears, but the fileConsent/invoke callback with action "accept" fails because the file was not registered in the provider pendingUploads store before sending the consent card. The CLI message send --media path does not pre-register the file.

Workaround

Upload files to the user OneDrive via Microsoft Graph API directly, then send a Teams message with the file link. This bypasses the consent flow entirely.
