fix(backend): stop Gitea/Forgejo pagination on empty page response

When an API token can only see a subset of org repos, the x-total-count
header reports the org total while the token returns fewer items. The
previous loop condition (output.length < totalCount) would never be
satisfied for the visible subset, causing infinite pagination.

Now we break out of the loop when the API returns an empty page,
matching the Gitea API pagination docs recommendation.

Fixes #1108
