Pine Invoice

-------invoice-------
1.When viewing a Draft Invoice, the Invoice Number field is displaying "Preview" instead of the actual invoice number. The system should display the generated invoice number even in draft mode to ensure proper identification and tracking of the invoice.
2. In the Custom Template, the header and footer sections are not being displayed properly. The content appears misaligned, cropped, or missing in the preview/output, affecting the overall document layout and readability.
----credit note-------
3.After creating and sending a Credit Note, if the sender downloads the Credit Note as a PDF or DOCX file, the status is automatically updated to "Viewed". However, the customer has not actually opened or viewed the Credit Note.
-------Recurring invoice-----
4.While creating a Recurring Invoice, the Digital Signature section is displayed. Since recurring invoices are generated automatically, the Digital Signature option should not be available during recurring invoice setup.
5.The Delete button is currently displayed in the Actions menu. As per the requirement, this option should not be available to users and should be removed from the Actions menu.
