From 620d3812d55d0e307eeac0bafdc9d1ea1ef7e904 Mon Sep 17 00:00:00 2001
From: Cursor Agent <cursoragent@cursor.com>
Date: Thu, 26 Feb 2026 20:46:21 +0000
Subject: [PATCH] refactor: annotate 24 Shared Razor files
 (Payment/Operations/Dialogs) with data source comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add bilingual (EN/VI) documentation comments to @code blocks explaining
the intended real data sources for each group:
- Payment (11 files): order context workflow state
- Operations (5 files): shift/cash management API
- Dialogs (8 files): current order/product context

Also add @using WebClientTpos.Client.Services to all 24 files for
future service integration pattern, plus @inject PosDataService
DataService to PendingOrders.razor specifically.

No UI template, CSS, or demo data changes — comments only.
