[Bug]: Remote shares are shown as internal shares

[kesselb]

Bug description

With Nextcloud 31, the share listing was reworked to display separate lists for internal and external shares.

However, when sharing a folder with a user on another instance by entering their address in the external shares input field, the share incorrectly appears under internal shares.

At the same time, adding a remote share via the internal shares input field does not work, which is inconsistent and confusing.

Expected behavior

Remote shares should be correctly categorized under external shares to avoid misclassification and ensure clarity.
