import command requires login even when --microcksURL is provided

Describe the bug

microcks import does not seem to handle --microcksURL the same way as import-dir.

I started a local Microcks instance using microcks start, which runs the latest-native image without Keycloak enabled. In this setup, importing through --microcksURL http://localhost:8585 should work without a saved login/config.

import-dir works correctly with an empty config path and imports the artifact successfully. But import with the same server URL and same empty config path fails with:

please login to perform this operation

This is confusing because the command already has the target server from --microcksURL.

Expected behavior

microcks import --microcksURL... should try to use the provided server directly, like --import-dir does. If the server requires authentication, then it
should fail with an auth/API error from the server.

The issue seems to be that cmd/import.go has its own client setup logic, while import-dir uses the shared newCommandClient(globalClientOpts) helper.

Repro

Microcks version or git rev

microcks-cli master branch

Install method (docker-compose, helm chart, operator, docker-desktop extension,...)

cmd/import.go から始め、クライアントのセットアップを import-dir による newCommandClient(globalClientOpts) の使用と比較します。--microcksURL と空の設定パスを使ってローカルサーバーに対してコマンドを再現します。完了条件は、保存済みのログインを要求せずに指定された URL が使用され、認証が必要なサーバーでは認証エラーまたは API エラーが返されることです。
