feat: Add manual email sending workflow and related database changes

- Implemented a new n8n workflow for manual email sending, including webhook trigger, order data fetching, email building, and sending. - Added logic to format email content with customer and order details. - Introduced new columns in the sales_orders table to track email sending status. - Updated database functions to handle new rental types and email status. - Created new RPCs for updating email status and retrieving email details for sales orders.
