fix: refine GLE deletion with against voucher check

[khushi8112]

Issue:

• A user was unable to delete an asset record, even after enabling the 'Delete Accounting and Stock Ledger Entries on Deletion of Transaction' option.
• The error occurred because the asset was linked to the GL entry through the 'against voucher' field, with the voucher type being 'Journal Entry'.
• The deletion logic was only validating the 'voucher type' but did not account for the 'against voucher' field, leading to the error.

Resolution:

• Updated the deletion logic to also check the 'against voucher' field in addition to the 'voucher type'.
