Implement proper path segment routing for user detail dialog

- Restore path segment routing: /admin/users/{userId}
- Add runGuardsAndResolvers to handle component reuse
- Move route parameter handling to ngOnInit for proper timing
- Make fetchUsers return Promise to handle async data loading
- Ensure dialog opens correctly even when component is reused
- Follows original requirement: query params -> path segments
