CLAUDE: Use DELETE endpoint for clearing draft list

The API now has a DELETE /draftlist/team/{team_id} endpoint
that properly clears a team's draft list.

Updated clear_list() to use the new endpoint instead of trying
to POST an empty list, which was failing with "list index out of range"
error because the API expected at least one entry to determine team_id.

This resolves the "Clear Failed" error when using /draft-list-clear.
