Feature request: Proper credit notes / corrective invoices for refunded orders

FluentCart currently creates a refund_notice, but it reuses the original order’s invoice_no. If the Order Receipt is intended to act as the customer’s official invoice, refunds should be able to generate a proper credit note/corrective invoice.

Ideally, this would include:

• A separate configurable numbering series and prefix.
• A new sequential number for every credit note.
• A link to the original invoice.
• Support for full and partial refunds.
• Correct tax/base adjustments.
• Its own PDF template, email attachment and customer-dashboard download.
• Hooks/API support for country-specific invoicing integrations.

The prefix and terminology could remain configurable, but the underlying document should be separate from the original invoice and from a simple refund confirmation.

Is this planned?
