Move all OCA POS modules from oca-technical to dedicated oca-pos submodule

Reorganized 74 POS-related modules for better structure:
- Moved all odoo-bringout-oca-pos-* packages from packages/oca-technical/
- Now organized in dedicated packages/oca-pos/ submodule
- Includes payment, receipt, loyalty, order, product, and partner modules
- Maintains all module functionality while improving project organization

This creates a cleaner separation between general technical modules
and Point of Sale specific functionality.

+In the javascript file, we could write
+
+.. code-block:: javascript
+
+    const PosDiscountAllOrder = () =>
+        class extends Order {
+        }
+
+However, this code doesn't work if ``pos_sale`` module is installed. For that
+reason we code the declaration as Odoo does, and add eslint exception.
+
+
+.. code-block:: javascript
+
+    // eslint-disable-next-line no-shadow
+    const PosDiscountAllOrder = (Order) =>
+        // eslint-disable-next-line no-shadow
+        class PosDiscountAllOrder extends Order {
+        }
