I would introduce a Draft status for invoices. Draft invoices are stored but are not visible to public queries or payable by customers until they are "finalized" by the merchant. I'm also good contributor with quality code & assurance.

Hello maintainer,

I am interested in implementing the "Draft" status for invoices to provide merchants with more control over their billing workflow. I will update the InvoiceStatus enum to include the Draft state and develop the finalize_invoice function to allow merchants to transition invoices to an active, payable status. My approach involves modifying the existing query logic to ensure draft invoices are filtered out of public views and adding a strict validation layer to prevent any payment attempts on invoices that have not yet been finalized.
