feat: remove Filament, add user account management

- Remove Filament /admin panel completely (AdminPanelProvider, UserResource, routes)
- Update composer.json to remove filament/filament dependency
- Add User model soft deletes with SoftDeletes trait + migration
- Strengthen UserPolicy::delete to prevent deleting last remaining admin
- Build out User module following pattern: CreateUserAction, UpdateUserAction, GetUsersAction,
  UserResource, UserController, Create/UpdateUserRequest, UserData DTO
- Add /api/users routes (index, store, update, destroy), all admin-gated via policy
- Create frontend Settings > Accounts page (settings/accounts.vue) for admin user management
- Add useUsers composable mirroring useClient pattern
- Add "Benutzer" link to settings dropdown in clients/index.vue
- All tests pass; User soft-delete and last-admin protection verified
