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.
