Added functionality to upload and manage receipts without initially associating them to a transaction, with the ability to map them later. Changes: - Modified Receipt model to make TransactionId nullable - Updated ReceiptManager service with new methods: - UploadUnmappedReceiptAsync: Upload receipts without a transaction - MapReceiptToTransactionAsync: Map an existing receipt to a transaction - Created Receipts page (Receipts.cshtml) with: - Upload form for new receipts - List view of all receipts (mapped and unmapped) - Status badges (Mapped/Unmapped) - Map to Transaction modal dialog - Delete receipt functionality - Added "Receipts" link to navigation menu - Fixed Transactions page receipt count query for nullable TransactionId - Created migration: MakeReceiptTransactionIdNullable This enables workflows where receipts are uploaded first and matched to transactions later, useful for batch receipt processing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
