Fix ClickUp multi-assignee time entry attribution for AI suggestions

I want Rize to correctly attribute time entries to the user who accepts an AI suggestion, even on multi-assignee ClickUp tasks. Currently, when I accept a suggestion for a task with multiple assignees, the time is often incorrectly logged under the first assignee in ClickUp (sometimes even a non-Rize user) instead of me. This is especially common when logging time for a previous day. This causes inaccuracies in our team's workload and time allocation.
