Invoices/Sales Admin Overview: Implement subtabs and add info about invoice status

[mariobehling]

The admin overview on the system sales need to be improved to ensure a smooth sales and invoicing process that can be taken care of by sales staff. Therefore:

• Separate the admin/sales tab into 2 subtabs - Orders and Invoices
• Move the sidebar table "Invoices" (https://eventyay.com/admin/sales/invoices) to its dedicated tab
• Make table sortable according to each column
• Enhance the Invoice table and implement missing tabs as follows. Show:
  • Invoice # (show with download link of Invoice PDF)
  • Invoice Date
  • Event
  • Dates
  • Amount
  • Organizer/Email (Show Names and Emails here)
  • Invoice Sent (Show dates invoice was sent out and also the dates if it was sent out several times)
  • Status (Unpaid, Overdue, Paid, Failed, Refunding, Refunded, Request Cancelled - Enable Admin to change the state; "Request Cancelled" means there was no invoice paid and the platform cancelled the request to pay the invoice)
  • Notify button (opening a pop-up with email options depending on state)
  • Resend Invoice button
