Add manual user creation in admin panel

- Server action createUser() with bcrypt password hash + Account record
- Form with name, email, password (show/hide + generate), role, emailVerified toggle
- Optional welcome email toggle (bypasses auto-hook for admin-created users)
- /admin/users/new page with breadcrumb navigation
- After creation, redirects to the new user's profile page
- "Добавить пользователя" button on the users list page
