BREAKING CHANGES:
- Removed OU=Roles from LDAP structure, role groups now created directly in department OU
- Role groups use ROLE_<Name> naming convention (similar to DEP_, POS_)
New features:
- RoleAssignment model: allows assigning roles to ANY employee, not just department members
- New API endpoints: /assign/, /revoke/, /assignments/ on DepartmentRoleViewSet
- Permission system updated: has_dept_perm() checks RoleAssignment first
- Employee profile shows external roles with 'внешняя роль' badge
- Employee list filter includes role-only employees with department_relation field
- Role assignment modal now searches all employees via AJAX
LDAP changes:
- _ensure_role_group(): creates ROLE_<Name> group in department OU
- assign_role(), revoke_role(): manage RoleAssignment + LDAP sync
- rename_role_group(), delete_role_group(): full lifecycle support
- Removed all references to OU=Roles
Migrations:
- 0035: Create RoleAssignment model
- 0036: Data migration from EmployeeDepartment.role
Tests:
- 7 new tests for role assignment (all passing)
Docs:
- 9 detailed reports on architecture, models, API, LDAP, tests
