feat: enhance multi-tenant UI and fix member aggregation

- adminfront: Update TenantListPage and UserListPage sorting logic to support all columns dynamically
- adminfront: Add inline 'Move', 'Remove', and 'Delete' actions directly inside the Tenant Org Chart member table
- adminfront: Remove redundant 'ACTIONS' column and profile icon from UserListPage, making the name clickable
- adminfront: Remove 'New Member' creation link from Tenant Org Chart 'Add Member' dropdown
- backend: Fix CountByCompanyCodes query to accurately aggregate user counts using both primary company_code and company_codes array
