feat: add companies as top-level container for projects with departments

- Company → Project → (Locations + Departments) hierarchy
- Company CRUD (add, edit, delete) with AJAX
- Projects are created under a company via inline strip
- Two-column project body: Locations | Departments
- Stats show companies, projects, locations, departments, active projects
- Dynamic stat counters update on add/delete without page reload
