Move all OCA HR modules from oca-technical to dedicated oca-hr submodule

Reorganized 67 HR-related modules for better structure:
- Moved all odoo-bringout-oca-hr-* packages from packages/oca-technical/
- Now organized in dedicated packages/oca-hr/ submodule
- Includes attendance, expense, holiday, employee, and contract modules
- Maintains all module functionality while improving project organization

This creates a cleaner separation between general technical modules
and HR-specific functionality.
