feat(auth): role management — ancestor completion, CRUD, permission assignment, cascade delete (ADR-0012)
Implements ADR-0005 (backend ancestor completion) and ADR-0012 (role management
architecture) across 5 tracer-bullet tickets:
- ISysMenuService.getAncestorIds: batch query full table, in-memory parentId
traversal, returns complete ancestor set (ADR-0005)
- SysRole.builtin field + DataInitializer idempotent refactor + 5 button
permission seeds (crm:role:list/detail/save/delete/assign) bound to ADMIN
- RoleController (/api/roles/*): page, saveOrUpdate, detail, assign-resources,
delete — pure hasAuthority, POST + action suffix, form params
- SysRoleServiceImpl.saveRole: roleCode uniqueness, builtin protection,
dataScope 1-4 range, create can't set builtin=true
- assignResources: calls getAncestorIds for ancestor completion, then
full replacement (delete + insert) of sys_role_menu
- getRoleDetail: returns RoleDetailVO with basic info + resourceIds
- deleteRoleCascade: cleans sys_role_menu + sys_user_role, builtin rejection,
three-table transaction
- SystemController: all role endpoints removed, unused deps cleaned
- Dead code removed: assignMenus, getMenuIdsByRoleId (superseded by
assignResources, getRoleDetail)
- H2 test schemas updated with builtin column
- 150 tests pass (16 new in SysRoleServiceImplTest, 7 in SysMenuServiceImplTest)
