Add a Reference of Original Accounting Estimate in Converted Invoices

[anuj-ever]

Issue:

Currently, when an accounting estimate is converted to an accounting invoice, there is no reference back to the original estimate. This makes it difficult for users to trace the payment back to its initial proposal, leading to potential confusion and incomplete audit trails.

Expected Condition:

When an accounting estimate is converted to an accounting invoice, there should be a clear reference back to the original accounting estimate. This will enable users to trace payments effectively and understand the transaction history, ensuring comprehensive documentation and improved financial tracking.
