fix: add attachment support for all transaction types

Fixed attachments not showing in edit forms for various transaction types by:

1. Adding @InjectAttachable() decorator to models:
   - SaleReceipt, SaleEstimate, CreditNote, PaymentReceived
   - Bill, BillPayment, VendorCredit
   - ManualJournal, Expense

2. Fixing transformers to include attachments in API responses:
   - SaleReceiptTransformer, PaymentReceivedTransformer

3. Registering missing event subscribers in Attachment.module.ts:
   - AttachmentsOnSaleReceipts, AttachmentsOnSaleEstimates

4. Fixing DocumentLink model relation mapping:
   - Changed Document.default to Document for proper module export

5. Fixing PaymentReceived model_ref consistency:
   - Changed from 'PaymentReceive' to 'PaymentReceived' to match class name

6. Adding missing withGraphFetched('attachments') to GetPaymentReceived.service.ts
