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.

+This module extends the functionality of Point of Sale module.
+
+By default, in Odoo a timeout is set to 30 seconds for the creation of
+a PoS order. This threshold is usually sufficient, but in some cases it is not,
+mainly if the connection is bad, or if some custom modules add extra
+long treatments.
+
+This module allows to change this default value.
+
+If the call contains more than one order (after a long disconnection period
+for example, or if the previous call raised the timeout) the effective timeout
+value applied will be equal to the defined timeout value multiplied by the
+number of orders.
