feat: Implement warehouse module roles with auto-schema repair and remove module access section

- Add SchemaVerifier class for automatic database schema verification and repair
- Implement warehouse_manager (Level 75) and warehouse_worker (Level 35) roles
- Add zone-based access control for warehouse workers
- Implement worker-manager binding system with zone filtering
- Add comprehensive database auto-repair on Docker initialization
- Remove Module Access section from user form (role-based access only)
- Add autocomplete attributes to password fields for better UX
- Include detailed documentation for warehouse implementation
- Update initialize_db.py with schema verification as Step 0
